Q141.

In an election, 95% of the total voters cast their votes. In this election, there were only two candidates A and B. The winner A, by obtaining 75% of the total votes, defeated his contestant B by 5500 votes. Find the total number of voters in the election.

एक चुनाव में, कुल मतदाताओं में से 95% ने अपने मत डाले। इस चुनाव में केवल दो उम्मीदवार A और B थे। विजेता A ने कुल मतों का 75% प्राप्त करके अपने प्रतिद्वंद्वी B को 5500 मतों से हराया। चुनाव में मतदाताओं की कुल संख्या ज्ञात कीजिए।

A12,000
B11,000
C13,000
D10,000

Show answer

Concept: Express both candidates' votes as % of total voters; the gap equals the winning margin.

Let total voters $= V$ . Votes cast $= 95 %$ of $V$ .
A gets $75 %$ of $V$ , so B gets $95 % - 75 % = 20 %$ of $V$ .
Margin $= 55 %$ of $V = 5500 \Rightarrow V = 10, 000$ .

Trick: Margin % = A% − B% = $75 - 20 = 55$ ; then $5500 \div 0.55$ .

Answer: (D) $10, 000$

अवधारणा: दोनों उम्मीदवारों के मत कुल मतदाताओं के % में लिखें; अंतर = जीत का अंतर।

कुल मतदाता $= V$ ; डाले गए मत $= 95 %$ ।
A को $V$ का $75 %$ , अतः B को $20 %$ ।
अंतर $= 55 % of V = 5500 \Rightarrow V = 10, 000$ ।

ट्रिक: अंतर % $= 75 - 20 = 55$ ; फिर $5500 \div 0.55$ ।

उत्तर: (D) $10, 000$

Q142.

A student goes to his school by cycle. The distance from his house to school is 5 km and he covers this distance in 1 hour. While going he stops twice for 5 minutes each. Find his average speed (in km/h).

एक विद्यार्थी साइकिल से अपने विद्यालय जाता है। उसके घर से विद्यालय की दूरी 5 km है और वह यह दूरी 1 घंटे में तय करता है। जाते समय वह दो बार 5-5 मिनट के लिए रुकता है। उसकी औसत चाल (km/h में) ज्ञात कीजिए।

A5.5
B6
C6.5
D4.5

Show answer

Concept: Here the speed asked is the cycling speed, i.e. distance ÷ actual moving time (stoppage time excluded).

Total time $= 60$ min; stoppages $= 2 \times 5 = 10$ min.
Moving time $= 50$ min $= \frac{5}{6}$ h.
Speed $= 5 \div \frac{5}{6} = 6 km/h$ .

Trick: Moving speed $= \frac{distance}{total time - stoppage time}$ .

Answer: (B) $6$

अवधारणा: यहाँ पूछी गई चाल साइकिल चलाने की चाल है, अर्थात दूरी ÷ वास्तविक चलने का समय (ठहराव का समय छोड़कर)।

कुल समय $= 60$ मिनट; ठहराव $= 10$ मिनट।
चलने का समय $= 50$ मिनट $= \frac{5}{6}$ घंटा।
चाल $= 5 \div \frac{5}{6} = 6 km/h$ ।

ट्रिक: चलने की चाल $= \frac{दूरी}{कुल समय - ठहराव समय}$ ।

उत्तर: (B) $6$

, then find the value of

\frac{4 a^{2} + 4 b^{2} + 4 c^{2}}{5 c^{2} - 8 a b}

यदि

2 a + 2 b + c = 0

है, तो

\frac{4 a^{2} + 4 b^{2} + 4 c^{2}}{5 c^{2} - 8 a b}

का मान ज्ञात कीजिए।

A $- 1$
B $1$
C $- 2 \sqrt{3}$
D $2 \sqrt{3}$

Show answer

Concept: Substitute $c = - 2 (a + b)$ from the given condition.

Numerator $= 4 a^{2} + 4 b^{2} + 16 (a + b)^{2} = 20 a^{2} + 20 b^{2} + 32 a b$ .
Denominator $= 20 (a + b)^{2} - 8 a b = 20 a^{2} + 20 b^{2} + 32 a b$ .
Ratio $= 1$ .

Trick: Put $a = b = 1$ : $c = - 4$ ; $\frac{4 + 4 + 64}{80 - 8} = \frac{72}{72} = 1$ .

Answer: (B) $1$

अवधारणा: दी गई शर्त से $c = - 2 (a + b)$ रखें।

अंश $= 20 a^{2} + 20 b^{2} + 32 a b$ ।
हर $= 20 (a + b)^{2} - 8 a b = 20 a^{2} + 20 b^{2} + 32 a b$ ।
अनुपात $= 1$ ।

ट्रिक: $a = b = 1$ रखें: $c = - 4$ ; $\frac{72}{72} = 1$ ।

उत्तर: (B) $1$

Q144.

A man borrowed ₹29,000 for 3 years and ₹45,000 for 5 years at the same rate of simple interest. If he paid a total interest of ₹62,400, then what was the rate of interest?

एक व्यक्ति ने साधारण ब्याज की समान दर पर ₹29,000, 3 वर्ष के लिए और ₹45,000, 5 वर्ष के लिए उधार लिए। यदि उसने कुल ₹62,400 ब्याज का भुगतान किया, तो ब्याज की दर क्या थी?

A18%
B20%
C27%
D25%

Show answer

Concept: $SI = \frac{P \times R \times T}{100}$ ; add the two interests.

$\frac{29000 \times 3 \times R}{100} + \frac{45000 \times 5 \times R}{100} = 62400$ .
$(87000 + 225000) \frac{R}{100} = 62400 \Rightarrow 3120 R = 62400$ .
$R = 20 %$ .

Trick: Sum of P×T: $312000$ ; 1% of it is 3120, and $62400 \div 3120 = 20$ .

Answer: (B) $20 %$

अवधारणा: $SI = \frac{P \times R \times T}{100}$ ; दोनों ब्याज जोड़ें।

$\frac{29000 \times 3 \times R}{100} + \frac{45000 \times 5 \times R}{100} = 62400$ ।
$3120 R = 62400$ ।
$R = 20 %$ ।

ट्रिक: P×T का योग $312000$ ; इसका 1% = 3120, $62400 \div 3120 = 20$ ।

उत्तर: (B) $20 %$

Q145.

If the radius of a sphere is increased by 20%, then find the percentage increase in its volume.

यदि एक गोले की त्रिज्या में 20% की वृद्धि की जाती है, तो इसके आयतन में प्रतिशत वृद्धि ज्ञात कीजिए।

A $68.5 %$
B $72.8 %$
C $70.6 %$
D $75.5 %$

Show answer

Concept: $V \propto r^{3}$ , so new volume factor $= (1.2)^{3}$ .

$(1.2)^{3} = 1.728$ .
Increase $= 72.8 %$ .

Trick: Successive 20% three times: $20 \to 44 \to 72.8$ .

Answer: (B) $72.8 %$

अवधारणा: $V \propto r^{3}$ , अतः नया आयतन गुणक $= (1.2)^{3}$ ।

$(1.2)^{3} = 1.728$ ।
वृद्धि $= 72.8 %$ ।

ट्रिक: 20% की तीन बार क्रमिक वृद्धि: $20 \to 44 \to 72.8$ ।

उत्तर: (B) $72.8 %$

4 \sqrt{7} π

वर्ग इकाई है, तो शंकु की त्रिज्या _______ इकाई है।

A $7$
B $7 \sqrt{7}$
C $\frac{\sqrt{7}}{7}$
D $\sqrt{7}$

Show answer

Concept: $l^{2} = r^{2} + h^{2}$ and curved surface area $= π r l$ .

Let $l = 4 k, h = 3 k$ ; then $r = \sqrt{16 k^{2} - 9 k^{2}} = \sqrt{7} k$ .
CSA $= π \times \sqrt{7} k \times 4 k = 4 \sqrt{7} π k^{2} = 4 \sqrt{7} π \Rightarrow k = 1$ .
Radius $= \sqrt{7}$ units.

Trick: Compare directly: $4 \sqrt{7} π k^{2}$ with $4 \sqrt{7} π$ ⇒ $k^{2} = 1$ .

Answer: (D) $\sqrt{7}$

अवधारणा: $l^{2} = r^{2} + h^{2}$ तथा वक्र पृष्ठ क्षेत्रफल $= π r l$ ।

$l = 4 k, h = 3 k$ ; $r = \sqrt{7} k$ ।
CSA $= 4 \sqrt{7} π k^{2} = 4 \sqrt{7} π \Rightarrow k = 1$ ।
त्रिज्या $= \sqrt{7}$ इकाई।

ट्रिक: $4 \sqrt{7} π k^{2}$ की तुलना $4 \sqrt{7} π$ से ⇒ $k^{2} = 1$ ।

उत्तर: (D) $\sqrt{7}$

Q149.

If a car runs at a speed of 60 km/h and takes 180 minutes to cover a certain distance, then what time will it take to cover the same distance at a speed of 40 km?

यदि एक कार 60 km/h की चाल से चलती है और एक निश्चित दूरी तय करने में 180 मिनट लेती है, तो 40 km की चाल से वही दूरी तय करने में उसे कितना समय लगेगा?

A4 hr 30 min4 घंटे 30 मिनट
B3 hr3 घंटे
C3 hr 15 min3 घंटे 15 मिनट
D3 hr 45 min3 घंटे 45 मिनट

Show answer

Concept: Distance $=$ speed $\times$ time; for the same distance, time ∝ $\frac{1}{speed}$ .

$180$ min $= 3$ h; distance $= 60 \times 3 = 180 km$ .
New time $= \frac{180}{40} = 4.5$ h $= 4$ hr $30$ min.

Trick: $3 \times \frac{60}{40} = 4.5$ h directly.

Answer: (A) 4 hr 30 min

अवधारणा: दूरी $=$ चाल $\times$ समय; समान दूरी के लिए समय ∝ $\frac{1}{चाल}$ ।

$180$ मिनट $= 3$ घंटे; दूरी $= 180 km$ ।
नया समय $= \frac{180}{40} = 4.5$ घंटे $= 4$ घंटे $30$ मिनट।

ट्रिक: $3 \times \frac{60}{40} = 4.5$ घंटे।

उत्तर: (A) 4 hr 30 min

Q150.

Two rectangular sheets of paper, each 60 cm × 36 cm, are made into two right circular cylinders, one by rolling the paper along its length and the other along the breadth. The ratio of the volumes of the two cylinders, thus formed, is:

कागज़ की दो आयताकार शीटों, जिनमें से प्रत्येक 60 cm × 36 cm की है, से दो लंब वृत्तीय बेलन बनाए जाते हैं, एक कागज़ को उसकी लंबाई के अनुदिश मोड़कर और दूसरा चौड़ाई के अनुदिश मोड़कर। इस प्रकार बने दोनों बेलनों के आयतनों का अनुपात है:

A5 : 6
B5 : 3
C8 : 3
D7 : 4

Show answer

Concept: The rolled edge becomes the circumference $2 π r$ ; the other side is the height. $V = π r^{2} h = \frac{C^{2} h}{4 π}$ .

Along length: $C = 60, h = 36$ ⇒ $V_{1} = \frac{60^{2} \times 36}{4 π}$ .
Along breadth: $C = 36, h = 60$ ⇒ $V_{2} = \frac{36^{2} \times 60}{4 π}$ .
$V_{1} : V_{2} = \frac{60^{2} \times 36}{36^{2} \times 60} = \frac{60}{36} = 5 : 3$ .

Trick: Ratio of volumes = ratio of the rolled sides: $60 : 36 = 5 : 3$ .

Answer: (B) 5 : 3

अवधारणा: जिस किनारे से मोड़ते हैं वह परिधि $2 π r$ बनता है; दूसरी भुजा ऊँचाई। $V = \frac{C^{2} h}{4 π}$ ।

लंबाई के अनुदिश: $C = 60, h = 36$ ।
चौड़ाई के अनुदिश: $C = 36, h = 60$ ।
$V_{1} : V_{2} = \frac{60^{2} \times 36}{36^{2} \times 60} = 5 : 3$ ।

ट्रिक: आयतनों का अनुपात = मोड़ी गई भुजाओं का अनुपात: $60 : 36 = 5 : 3$ ।

Q151.

Select the most appropriate meaning of the given idiom.
Make waves

ATo cause difficulty
BTo give up
CTo take it easy
DTo have patience

Show answer

Concept: Make waves means to create trouble or disturbance, to upset the existing situation.

Waves disturb calm water; similarly, a person who 'makes waves' causes problems or stirs controversy.
Example: The new manager made waves by questioning old rules.
(B) 'give up', (C) 'take it easy', (D) 'have patience' all suggest calmness or quitting – the opposite idea.

Trick: Calm water vs. waves – waves = trouble.

Answer: (A) To cause difficulty

अवधारणा: Make waves का अर्थ है परेशानी या हलचल पैदा करना, स्थिति को बिगाड़ना।

शांत पानी में लहरें हलचल लाती हैं; वैसे ही 'make waves' करने वाला व्यक्ति समस्या या विवाद खड़ा करता है।
उदाहरण: The new manager made waves by questioning old rules.
(B) छोड़ देना, (C) आराम से लेना, (D) धैर्य रखना – ये सब शांति/हार मानने के भाव हैं, अतः गलत।

ट्रिक: शांत पानी बनाम लहरें – लहरें = परेशानी (difficulty)।

Select the INCORRECTLY spelt word.

AMatriculation
BProhibition
CHumorous
DAddmission

Show answer

Concept: Correct spelling: Admission – only one 'd' after 'A'.

The word comes from admit (ad + mit) – a single 'd'.
Admit → Admission (double 's' only).
Matriculation, Prohibition, Humorous are all correctly spelt.

Yaad rakhein: Admit has one 'd', so Admission also has one 'd'.

Answer: (D) Addmission

अवधारणा: सही वर्तनी: Admission – 'A' के बाद केवल एक 'd'।

यह शब्द admit से बना है – इसमें एक ही 'd' है।
Admit → Admission (केवल 's' दोहरा है)।
Matriculation, Prohibition, Humorous सही वर्तनी में हैं।

याद रखें: Admit में एक 'd' है, इसलिए Admission में भी एक ही 'd'।

Q153.

Parts of the following sentence have been given as options. Select the option that
contains an error.
For the past / three years, / my uncle is /away from home.

Athree years,
BFor the past
Cmy uncle is
Daway from home.

Show answer

Concept: An action continuing from a past point up to now, with 'for the past …', needs the present perfect tense.

'For the past three years' shows a period starting in the past and continuing till now.
Simple present 'is' cannot express this; use 'has been'.
Correct: For the past three years, my uncle has been away from home.

Trick: 'for/since/for the past' + continuing state → has/have been.

Answer: (C) my uncle is

अवधारणा: भूतकाल से अब तक चल रही स्थिति के लिए 'for the past …' के साथ present perfect (has been) आता है।

'For the past three years' – समय-अवधि जो भूतकाल में शुरू होकर अब तक जारी है।
Simple present 'is' यह भाव नहीं देता; 'has been' चाहिए।
सही वाक्य: For the past three years, my uncle has been away from home.

ट्रिक: for/since/for the past + जारी स्थिति → has/have been।

उत्तर: (C) my uncle is

Select the most appropriate option that can substitute the underlined words in the
given sentence.
My grandmother helps us in all the problems. She has a remedy for all the diseases.

A‘Service’
BPanacea
CFanatic
DHeretic

Show answer

Concept: Panacea = a remedy for all diseases or problems; a cure-all.

Greek pan = all + akos = cure → cure for all.
Fanatic = person with extreme zeal; Heretic = one who opposes accepted beliefs; 'Service' is unrelated.
So 'a remedy for all the diseases' = panacea.

Trick: Pan = all (Pan-India, Panorama) → Panacea = cure for all.

Answer: (B) Panacea

अवधारणा: Panacea = सभी रोगों/समस्याओं का इलाज (रामबाण)।

Greek pan = सब + akos = इलाज → सबका इलाज।
Fanatic = कट्टर व्यक्ति; Heretic = प्रचलित धार्मिक मान्यताओं का विरोधी (विधर्मी); 'Service' असंबंधित है।
अतः 'a remedy for all the diseases' = Panacea।

ट्रिक: Pan = सब (Pan-India) → Panacea = सबका इलाज (रामबाण)।

उत्तर: (B) Panacea

Q155.

In the question four alternatives are given for the underlined word in the sentence. Choose the alternative which best expresses the opposite meaning of the word.
We embraced each other overjoyed at our success, then I took photograph of Tenzing holding aloft the flags of Great Britain, Nepal, the United Nations and India.”

ACradled
BJunked
CContained
DLimited

Show answer

Concept: Embrace means to hold someone closely in one's arms (hug), or to accept something eagerly and willingly. Its opposite is to reject, discard or throw away.

In the sentence, the climbers hugged each other in joy, i.e. they held each other close.
Junked = discarded, thrown away as useless – the act of pushing away/rejecting, which is the opposite of holding close and accepting.
Cradled = held gently in the arms; Contained = held within – both are close to the meaning of embraced.
Limited = restricted; it is not the opposite of holding or accepting.

Trick: embrace ↔ reject / discard / junk; embrace ≈ hug, cradle, welcome.

Answer: (B) Junked

अवधारणा: Embrace का अर्थ है किसी को बाँहों में भर लेना (गले लगाना) या किसी चीज़ को खुशी से स्वीकार करना। इसका विलोम है reject, discard यानी ठुकराना या फेंक देना।

वाक्य में पर्वतारोही सफलता की खुशी में एक-दूसरे को गले लगाते हैं।
Junked = बेकार समझकर फेंक देना/त्याग देना – यह पास रखने और अपनाने का ठीक उल्टा है।
Cradled = बाँहों में सहेज कर पकड़ना; Contained = अपने भीतर रखना – दोनों embraced के समान अर्थ वाले हैं।
Limited = सीमित किया गया; यह गले लगाने या स्वीकारने का विलोम नहीं है।

याद रखें: embrace ↔ reject / discard / junk; embrace ≈ hug, cradle, welcome.

उत्तर: (B) Junked

Q156.

Select the INCORRECTLY spelt word.

AInterogative
BAuditions
CInterference
DGreengrocers

Show answer

Concept: Correct spelling: Interrogative – double 'r'.

The word comes from inter + rogare (to ask) → inter + rogative = interrogative.
Auditions, Interference, Greengrocers are correctly spelt.
Hence 'Interogative' is misspelt.

Yaad rakhein: Interrogate, Interrupt, Irregular – prefix ends in 'r' and root starts with 'r' → 'rr'.

Answer: (A) Interogative

अवधारणा: सही वर्तनी: Interrogative – दो 'r'।

यह inter + rogare (पूछना) से बना है → inter + rogative।
Auditions, Interference, Greengrocers सही हैं।
अतः 'Interogative' गलत वर्तनी है।

याद रखें: Interrogate, Interrupt – inter + r… → 'rr'।

उत्तर: (A) Interogative

He is feeding a male dog and female dog

Aa dog and puppy
Ba dog and a bitch
Ca male dog and lady dog
DNo substitution

Show answer

Concept: Many animals have separate words for male and female; we use those words instead of adding 'male'/'female'. Male dog = dog, female dog = bitch.

Standard gender pair: dog – bitch (like horse – mare, lion – lioness).
Each noun takes its own article: 'a dog and a bitch'.
'puppy' = young dog, not female; 'lady dog' is not standard English.

Yaad rakhein: Gender pairs: dog–bitch, horse–mare, fox–vixen, drake–duck.

Answer: (B) a dog and a bitch

अवधारणा: कई जानवरों के नर और मादा के लिए अलग शब्द होते हैं; 'male/female' जोड़ने के स्थान पर वही शब्द प्रयोग होता है। नर कुत्ता = dog, मादा = bitch।

मानक लिंग-युग्म: dog – bitch (जैसे horse – mare, lion – lioness)।
दोनों संज्ञाओं के साथ अलग article: 'a dog and a bitch'।
'puppy' = पिल्ला (मादा नहीं); 'lady dog' मानक अंग्रेज़ी नहीं है।

याद रखें: लिंग-युग्म: dog–bitch, horse–mare, fox–vixen, drake–duck।

उत्तर: (B) a dog and a bitch

The quality of students of an educational institute is of great importance and a crucial starting point.

AThe quality of students in an educational institute is in great importance and a crucial starting point.
BThe quality of students in an educational institute is of great importance and a crucial starting point.
CNo substitution
DThe quality of students in an educational institute is of great importance and is a
crucial start point.

Show answer

Concept: Students study in an institute; 'of great importance' is the fixed phrase; 'starting point' is the correct compound noun.

'students of an institute' → better 'students in an educational institute'.
'is of great importance' is correct ('in great importance' is wrong) – so (A) is out.
(D) uses 'start point', which is not the standard expression ('starting point').
(B) corrects the preposition and keeps everything else right.

Trick: be + of + importance/value/use (of great importance, of no use).

Answer: (B) The quality of students in an educational institute is of great importance and a crucial starting point.

अवधारणा: छात्र किसी संस्थान में (in) पढ़ते हैं; 'of great importance' निश्चित वाक्यांश है; 'starting point' सही संयुक्त संज्ञा है।

'students of an institute' → बेहतर 'students in an educational institute'।
'is of great importance' सही है ('in great importance' गलत) – अतः (A) गलत।
(D) में 'start point' है, जो मानक नहीं ('starting point' सही)।
(B) में preposition सही है और बाकी भी सही।

ट्रिक: be + of + importance/value/use (of great importance, of no use)।

उत्तर: (B) The quality of students in an educational institute is of great importance and a crucial starting point.

Show answer

Concept: A singular subject (one organisation's name) takes a singular verb.

'The Centre for Policy Research' is one body – a singular subject.
Present tense singular verb needs '-s': estimates.
Correct: …the Centre for Policy Research estimates that India has the largest stock…
'Although there is no proven data' and 'India has the largest stock' are correct.

Trick: Name of one organisation = singular → verb + s.

Answer: (B) Centre for Policy Research estimate

अवधारणा: एकवचन कर्ता (एक संस्था का नाम) के साथ एकवचन क्रिया आती है।

'The Centre for Policy Research' एक संस्था है – एकवचन कर्ता।
Present tense एकवचन क्रिया में '-s' लगेगा: estimates।
सही: …the Centre for Policy Research estimates that India has the largest stock…
बाकी भाग सही हैं।

ट्रिक: एक संस्था का नाम = एकवचन → verb + s।

उत्तर: (B) Centre for Policy Research estimate

Show answer

Concept: In indirect speech with a past reporting verb ('asked'), the present tense of the reported question shifts to the past.

Reporting verb 'asked' is in the past tense.
Hence 'is' → was, matching 'worked' in the same sentence.
Correct: She asked me where my hometown was and where I worked.
'has been', 'would be', 'were' do not follow the rule here.

Trick: Past reporting verb → is → was, works → worked.

Answer: (D) hometown was

अवधारणा: अप्रत्यक्ष कथन में reporting verb भूतकाल ('asked') हो तो reported प्रश्न का present tense भूतकाल में बदल जाता है।

'asked' भूतकाल में है।
अतः 'is' → was, जो उसी वाक्य के 'worked' से मेल खाता है।
सही: She asked me where my hometown was and where I worked.
'has been', 'would be', 'were' यहाँ नियम के अनुसार नहीं।

ट्रिक: Past reporting verb → is → was, works → worked।

उत्तर: (D) hometown was
