Q1.
Choose the address that is the same as the one given below.
House No. 77, Sector 19, Chandigarh - 160019
नीचे दिए गए पते के समान पता चुनिए।
House No. 77, Sector 19, Chandigarh - 160019
  1. AHouse No. 77, Sector 19, Punjab - 160019
  2. BHouse No. 77, Sector 19, Chandigarh - 160019
  3. CHouse No. 77, Sector 19, Haryana - 160019
  4. DHouse No. 77, Sector 19, Delhi - 160019
Show answer

Concept: Compare every part of the address — number, sector, city, PIN — with the given one.

  1. House No. 77, Sector 19 and PIN 160019 are identical in all four options.
  2. The only changing part is the city/state: Punjab, Chandigarh, Haryana, Delhi.
  3. Given address says Chandigarh → only option (B) matches fully.

Trick: Skip the parts that are common to all options; check only the part that varies.

Answer: (B) House No. 77, Sector 19, Chandigarh - 160019

अवधारणा: पते के हर भाग — मकान नं., सेक्टर, शहर, PIN — की दिए गए पते से तुलना करें।

हल:

  1. मकान नं. 77, सेक्टर 19 और PIN 160019 चारों विकल्पों में एक जैसे हैं।
  2. केवल शहर/राज्य बदल रहा है: Punjab, Chandigarh, Haryana, Delhi।
  3. दिए गए पते में Chandigarh है → पूरी तरह मेल केवल (B) में।

ट्रिक: जो भाग सभी विकल्पों में समान हो उसे छोड़ दें, सिर्फ बदलने वाला भाग जाँचें।

उत्तर: (B) House No. 77, Sector 19, Chandigarh - 160019

Q26.
What unique feature sets ISRO's Aditya-L1 mission apart from other solar observation missions?
इसरो के आदित्य-L1 मिशन की कौन-सी विशेषता उसे अन्य सौर प्रेक्षण मिशनों से अलग करती है?
  1. AIt collects solar data from Lagrange Point 1 to observe the Sun's coronaयह लैग्रेंज बिंदु 1 से सौर आँकड़े जुटाकर सूर्य के कोरोना का प्रेक्षण करता है
  2. BIt revolves around the Earth's geostationary orbitयह पृथ्वी की भूस्थिर कक्षा में परिक्रमा करता है
  3. CIt operates from a Mars transfer trajectoryयह मंगल स्थानांतरण पथ से कार्य करता है
  4. DIt uses infrared imaging from low Earth orbitयह निम्न भू-कक्षा से अवरक्त प्रतिबिंबन करता है
Show answer

Concept: Aditya-L1 observes the Sun from the Sun–Earth Lagrange point L1.

  1. Launched by ISRO in September 2023 (PSLV-C57); placed in a halo orbit around L1, ~15 lakh km from Earth.
  2. At L1 the Sun is never hidden by Earth, so it gives non-stop views of the corona, chromosphere and solar wind.
  3. Geostationary, Mars-transfer or low-Earth orbits are not where it works.

Yaad rakhein: L1 = point where Sun's and Earth's gravity balance; NASA–ESA's SOHO also sits there.

Answer: (A) It collects solar data from Lagrange Point 1 to observe the Sun's corona

अवधारणा: आदित्य-L1 सूर्य–पृथ्वी लैग्रेंज बिंदु L1 से सूर्य का अध्ययन करता है।

हल:

  1. ISRO ने सितंबर 2023 में PSLV-C57 से प्रक्षेपित किया; यह पृथ्वी से लगभग 15 लाख km दूर L1 के चारों ओर हेलो कक्षा में है।
  2. L1 से सूर्य कभी पृथ्वी की ओट में नहीं आता, अतः कोरोना, क्रोमोस्फीयर और सौर पवन का लगातार अवलोकन होता है।
  3. भूस्थिर, मंगल-पथ या निम्न भू-कक्षा इसका कार्यक्षेत्र नहीं है।

याद रखें: L1 वह बिंदु है जहाँ सूर्य और पृथ्वी का गुरुत्व संतुलित होता है; SOHO भी यहीं है।

उत्तर: (A) यह लैग्रेंज बिंदु 1 से सौर आँकड़े जुटाकर सूर्य के कोरोना का प्रेक्षण करता है

Q51.
Simplify: 11+46
सरल कीजिए: 11+46
  1. A23 + 3
  2. B22 + 3
  3. C11 + 5
  4. D23 + 2
Show answer

Concept: √(x + y + 2√(xy)) = √x + √y.

  1. 4√6 = 2√24, so we need x + y = 11 and xy = 24.
  2. x = 8, y = 3 → 11 + 4√6 = (√8 + √3)².
  3. √(11 + 4√6) = √8 + √3 = 2√2 + √3.

Trick: Square the options: (2√2 + √3)² = 8 + 3 + 4√6 = 11 + 4√6 ✓.

Answer: (B) 2√2 + √3

अवधारणा: √(x + y + 2√(xy)) = √x + √y।

हल:

  1. 4√6 = 2√24, अतः x + y = 11 और xy = 24 चाहिए।
  2. x = 8, y = 3 → 11 + 4√6 = (√8 + √3)²।
  3. √(11 + 4√6) = √8 + √3 = 2√2 + √3।

ट्रिक: विकल्प का वर्ग करें: (2√2 + √3)² = 8 + 3 + 4√6 = 11 + 4√6 ✓।

उत्तर: (B) 2√2 + √3

Q76.
Select the option that expresses the given sentence in the Active/Passive voice.
The children will finish their homework by dinner time.
  1. ATheir homework will be finished by the children by dinner time.
  2. BTheir homework is finished by the children by dinner time.
  3. CTheir homework would be finished by the children by dinner time.
  4. DTheir homework has been finished by the children by dinner time.
Show answer

Concept: Simple future passive = will be + V3.

  1. Active: 'will finish' (simple future); object 'their homework' becomes subject.
  2. Passive: Their homework will be finished by the children by dinner time.
  3. 'is finished' (present), 'would be' (conditional), 'has been' (present perfect) change the tense.

Trick: Tense never changes in voice change — keep 'will', add 'be' + V3.

Answer: (A) Their homework will be finished by the children by dinner time.

अवधारणा: Simple future का passive = will be + V3।

हल:

  1. Active में 'will finish' (simple future) है; object 'their homework' अब subject बनेगा।
  2. Passive: Their homework will be finished by the children by dinner time.
  3. 'is finished' (present), 'would be', 'has been' — ये tense बदल देते हैं।

ट्रिक: Voice बदलने पर tense नहीं बदलता — 'will' रखें, 'be' + V3 जोड़ें।

उत्तर: (A) Their homework will be finished by the children by dinner time.
