Sample questions from this paper

Q1.
Choose the correct option to fill in the blank in the sentence given: When completing registration forms, it is
____ to provide your full address and contact number.
  1. Amandatory
  2. Bunnecessary
  3. Ccustomary
  4. Dchoice
Show answer

Concept: Pick the word that fits the sense of a compulsory requirement.

  1. Forms ask for address and phone as a must, not as a choice.
  2. Mandatory = compulsory, required by rule → 'it is mandatory to provide…'
  3. 'Unnecessary' gives the opposite idea; 'customary' = usual by habit; 'choice' is a noun and does not fit after 'it is'.

Trick: After 'it is ___ to do something', you need an adjective; 'choice' (noun) is out at once.

Answer: (A) mandatory

अवधारणा: वाक्य के भाव के अनुसार 'अनिवार्य' अर्थ वाला शब्द चुनना है।

हल:

  1. Registration form में पता और फोन नंबर देना ज़रूरी होता है।
  2. Mandatory = अनिवार्य/आवश्यक – वाक्य पूरा अर्थ देता है।
  3. Unnecessary = अनावश्यक (उल्टा अर्थ), customary = रिवाज़ के अनुसार, choice = संज्ञा, यहाँ adjective चाहिए।

ट्रिक: 'it is ___ to …' के बीच adjective आता है, इसलिए noun 'choice' तुरंत हटाएँ।

उत्तर: (A) mandatory

Q26.
Find the next element that replace the ?
Logically
10,7,1,-11,?
उस अगले पद को ज्ञात कीजिए जो प्रश्नवाचक चिह्न (?) का स्थान लेगा।
तार्किक रूप से
10,7,1,-11,?
  1. A-35
  2. B-32
  3. C-36
  4. D-38
Show answer

Concept: Find the pattern in the differences.

  1. Gaps: 10→7 is −3, 7→1 is −6, 1→−11 is −12.
  2. Gaps double: 3, 6, 12, 24.
  3. Next term = −11 − 24 = −35.

Trick: If differences look like 3, 6, 12 – think ×2 at once; only −35 is 24 below −11.

Answer: (A) -35

अवधारणा: अंतरों का पैटर्न देखें।

हल:

  1. अंतर: −3, −6, −12।
  2. हर बार अंतर दोगुना: 3, 6, 12, 24।
  3. अगला पद = −11 − 24 = −35।

ट्रिक: अंतर 3, 6, 12 दिखें तो सीधे ×2 सोचें; −11 से 24 कम = −35।

उत्तर: (A) -35

Q51.
In an electronic circuit, the signal strength is given by ((a+b)2+(a−b)2)2. Find the simplified expression.
एक इलेक्ट्रॉनिक परिपथ में सिग्नल की तीव्रता ((a+b)2+(a−b)2)2 द्वारा दी जाती है। सरलीकृत व्यंजक ज्ञात कीजिए।
  1. A4a2+4b2
  2. B16a2+16b2
  3. C4a4+8a2b2+4b4
  4. D8a2+8b2
Show answer

Concept: (a+b)² + (a−b)² = 2(a² + b²).

  1. Inner bracket = 2(a² + b²) (the ±2ab terms cancel).
  2. Square it: 4(a² + b²)².
  3. Expand: 4(a⁴ + 2a²b² + b⁴) = 4a⁴ + 8a²b² + 4b⁴.

Trick: Put a = b = 1: (4 + 0)² = 16. Option C gives 4 + 8 + 4 = 16 ✓; A gives 8, B 32, D 16 – but D is only degree 2, so C.

Answer: (C) 4a⁴ + 8a²b² + 4b⁴

अवधारणा: (a+b)² + (a−b)² = 2(a² + b²)।

हल:

  1. अंदर का कोष्ठक = 2(a² + b²) (±2ab कट जाते हैं)।
  2. वर्ग करें: 4(a² + b²)²।
  3. विस्तार: 4a⁴ + 8a²b² + 4b⁴।

ट्रिक: a = b = 1 रखें: (4)² = 16; विकल्प C = 4 + 8 + 4 = 16 ✓। D भी 16 देता है पर उसकी घात 2 है, जबकि उत्तर घात 4 का होना चाहिए।

उत्तर: (C) 4a⁴ + 8a²b² + 4b⁴
