Explanation

Place E, A, D together and B second to the right of E; F sits between B and G. Going clockwise the order is E, A, D, G, F, B, C, so G is second to the left of A.

Explanation

She goes 6 + 3 = 9 m east and 4 + 8 = 12 m south in total. Shortest distance = √(9² + 12²) = √225 = 15 m.

Explanation

After replacing the signs the expression is 35 ÷ 7 × 8 + 25 − 2 = 5 × 8 + 25 − 2 = 40 + 23 = 63.

Explanation

The order is Ram > Varun > Mohit > Jayant > Dutta > Keshav, so Ram is the tallest.

Explanation

"Some whites are lights" and "All lights are candles" give "Some candles are whites", so II follows. Nothing definitely links dogs to lights or candles, so I and III do not follow.

Explanation

The differences are 7, 14, 21, 28, so the next difference is 35: 74 + 35 = 109.

Explanation

Both arguments give a relevant, direct benefit of youth entrepreneurship (industrial growth and less pressure on the job market), so both are strong.

Explanation

M is the sister of T, T is the son of F, and F is the father of H. So M is F's daughter and H is F's child, which makes M the sister of H.

Explanation

Round off: 46 − 95 ÷ 19 + 35 × 8 = 46 − 5 + 280 = 321.

Explanation

49 = 7², 64 = 8² and 81 = 9², but 11² = 121, not 120. So 120-11 is the odd pair.

Explanation

50 × 4 − 10 = 190, 46 × 4 − 10 = 174 and 30 × 4 − 10 = 110, but 18 × 4 − 10 = 62, not 72. So 18-72 is different.

Explanation

A water image flips the figure top to bottom. The semicircle moves from the bottom-left to the top-left, and the hook moves from the top-right to the bottom-right with its arm pointing down. Option C shows exactly this.

Explanation

The pairs are P-O, P-T, P-V, I-E and T-V, which makes 5 pairs. So the answer is more than three.

Explanation

Each of KP, IR and FU is an opposite-letter pair whose positions add up to 27 (11+16, 9+18, 6+21). CY gives 3 + 25 = 28, so it is the odd one.

Explanation

DEHG, RSVU and JKNM all follow +1, +3, −1. LMQP follows +1, +4, −1, so it is different.

Explanation

The C's followed by a vowel are the two in "CACA", the C in "CCU" and the C in "FCAU". That makes 4.

Explanation

The bottom letter of each figure is the top letter of the figure before it, and the crossed lines alternate. So the next figure has V at the bottom and a new symbol (the arrow) at the top, as in option C.

Explanation

A mirror on the right flips the figure left to right. The arrow moves from the top-left to the top-right, and the diagonal changes from / to \. Option A shows this.

Explanation

Passed girls = 12 + 41 − 1 = 52. Adding 3 girls who did not appear and 1 who failed gives 56.

Explanation

After swapping 20 and 18: 40 + 18 × 65 ÷ 13 − 20 = 40 + 18 × 5 − 20 = 40 + 90 − 20 = 110.

Explanation

The dance hall of the Konark Sun Temple is called the Nata Mandir. The Jagamohana is the assembly hall (porch), and the Shikhara and Vimana are towers.

Explanation

Volume of the hemisphere = (2/3)πr³ with r = 2.8 m, which is about 45.995 m³ = 45,995 litres. Half of it is about 22,997 L, and at 5 L/s that takes about 4,599 s ≈ 76.66 minutes.

Explanation

Let p = aq + b/q. From p = 21 at q = 5 and p = 13⅔ at q = 3 we get a = 4 and b = 5. Check: 4(5) + 5/5 = 21 and 4(3) + 5/3 = 13⅔.

Explanation

The extra saving is 21% − 15% = 6% of the labelled price. 6% = ₹540, so the labelled price = 540 × 100/6 = ₹9,000.

Explanation

She covers 4 km in (3/5) × 40 = 24 minutes. The other 4 km must be done in 16 minutes, so speed = 4 ÷ (16/60) = 15 km/h.

Explanation

Let the first number be x. Then x + 3x + 5x = 3 × 12 = 36, so 9x = 36 and x = 4. The smallest number is 4.

Explanation

1452 = 2² × 3 × 11². The prime 3 has an odd power, so multiply by 3: 1452 × 3 = 4356 = 66².

Explanation

In powers of 5: the numerator is 5^10.8 × 5^6.2 = 5^17 and the denominator is 5^12.6 × 5^3.4 = 5^16. So the value is 5^(17 − 16) = 5.

Explanation

Old income = 15,000 + 3,000 = 18,000. New income = 20,700 and new savings = 3,150, so the new expenditure is 17,550. The increase is ₹2,550.

Explanation

There are 240 males and 192 females. Males stay at 240, and 240 : F = 3 : 5 gives F = 400. So 400 − 192 = 208 new female employees joined.

Explanation

Cutting at half the height leaves a small cone with half the radius and half the slant height, so its curved surface area is 1/4 of the original. The frustum therefore has 3/4 of it, and the ratio is 1 : 3/4 = 4 : 3.

Explanation

Let the boat speed be u: 24/(u − 3) + 24/(u + 3) = 1.8 gives u = 27. So upstream speed = 24 km/h and downstream speed = 30 km/h. Time = 38.4/24 + 42/30 = 1.6 + 1.4 = 3 hours.

Explanation

The shares are 2000, 1600 and 3600. Adding 400 to each gives 2400, 2000 and 4000, which is 6 : 5 : 10.

Explanation

Boys in C = 800. Girls in B = 5% of 5000 − 150 = 250 − 150 = 100. Total in E = 35% of 5000 = 1750. The ratio 800 : 100 : 1750 = 16 : 2 : 35.

Explanation

A single 39% discount leaves 61% of the marked price. Successive 15% and 20% discounts leave 0.85 × 0.8 = 68%. The difference of 7% = ₹112, so the marked price = ₹1,600.

Explanation

Let A take x days and B take x + 6 days: 1/x + 1/(x + 6) = 5/36 gives x = 12. So A does 1/3 of the work in 12/3 = 4 days.

Explanation

The amount for one extra year is 11,027.30 ÷ 10,210.46 = 1.08, so the rate is about 8%.

Explanation

Total age = 15 × 28 = 420 and the new total = 20 × 30 = 600. The five new students add 180 years, an average of 36 years.

Explanation

The number is 360 ÷ 0.8 = 450. To reach 585 it must increase by 135, and 135/450 = 30%.

Explanation

ECE/CSE = 20%/30% = 2/3, which is about 66.7% ≈ 67%.

Explanation

Let the faster pipe take x minutes and the slower one 2x. Then 1/x + 1/(2x) = 3/(2x) = 1/42, so x = 63. The slower pipe takes 126 minutes.

Explanation

"Daily morning" is not idiomatic English. It should be "every morning" (or just "daily"). The verb "collects" correctly agrees with the nearer subject, "their father".

Explanation

"To get someone's goat" means to annoy or irritate someone.

Explanation

The correct spellings are "government", "stubbornly", "refused" and "voluminous", and only option A uses all of them.

Explanation

The correct spelling is "embarrass", with a double r and a double s.

Explanation

Sentence 4 introduces Everest and the first 1924 attempt. Sentence 1 tells how Mallory and Irvine vanished, sentence 3 covers the later Hillary-Tenzing success, and sentence 2 contrasts Tenzing ("on the other hand").

Explanation

The past narrative needs "led" and "stood". "Running" is a participle describing the lane, and "hear them talking" uses the -ing form after a verb of perception.

Explanation

A recluse is a person who lives alone and avoids other people. A cleric or priest is a religious official, and a stoic is someone who endures pain calmly.

Explanation

Sentence 3 introduces Everest's bad image and sentence 4 describes the litter. Sentence 1 then gives the new rule, and sentence 2 explains the eight kilograms mentioned in it.

Explanation

"Make sure you work hardest" is wrong because no comparison is being made. The adverb should be in its plain form: "work hard".

Explanation

"No sooner" is followed by "had + subject + past participle", so the correct form is "No sooner had she finished … than".

Explanation

"Venerated" means deeply respected. Its opposite is "despised", meaning looked down upon or hated.

Explanation

Habitual present needs "says". "Get to know" takes the base form, and "the people who live" is plural. "See eye to eye" also uses the base form after "don't".

Explanation

"On her own" means alone, without anyone else. That fits "she should not be left on her own".

Explanation

The proverb means that being apart from someone we love makes us feel more affection for them.

Explanation

"Spruce up" means to make neat or smarter, and a spruce is also a kind of conifer tree. So the same word fits both blanks.

Explanation

"Deity" means a god. The most nearly opposite option is "ogre", a cruel monster or evil being, as opposed to a divine one.

Explanation

The passage says that when people "turned to" food production, the Mother Goddess became the "chief deity". The option saying they "overlooked" food production and calls her a "pagan symbol" is not a fact from the passage.

Explanation

The passage describes sacred trees, why they were worshipped and how tree shrines developed. It does not set out causes and effects or comparisons, so its structure is descriptive.

Explanation

"Adoration" means deep love and worship. "Glorification", meaning praising or honouring, is the closest in meaning.

Explanation

The passage keeps returning to tree worship being ancient ("probably the oldest form of worship"), so the best title is "Trees – The Oldest Form Of Worship".

Explanation

गद्यांश के अनुसार पंजाब में यूनियनिस्ट पार्टी ने सरकार बनाई थी।

Explanation

गद्यांश में लिखा है कि कांग्रेसी मंत्रियों ने पुलिस के अधिकार कम किए। अतः 'पुलिस के अधिकार बढ़ाए गए' वाला निर्णय नहीं लिया गया।
