The reward is only for records broken fairly. XYZ was found under the influence of a banned drug, so he will not get the reward (II follows). Nothing shows the accusation was false (I does not follow).

Mutation theory (Hugo de Vries) says new species arise from sudden, large, heritable changes in traits, unlike Darwin's gradual natural selection.

The Colosseum is in Italy; the rock-cut city of Petra is in Jordan. Both are among the New Seven Wonders of the World.

Positivism (Auguste Comte) accepts only knowledge that can be verified scientifically or proved logically or mathematically, and rejects metaphysics and theism.

147 runs out of 210 is 70% of the runs, not 70% of the team (I fails), and nothing is said about who opened the batting (II fails). Neither follows.

CP of 12 books = SP of 8 books. Take CP of a book = 1: SP of 8 books = 12, so SP of 1 book = 1.5. Gain = 50%.

Let the coins be 2x, 4x and 5x. Value = 2x + 8x + 25x = 35x = 455, so x = 13 and the number of Rs 2 coins = 4x = 52.

A function used inside another function, e.g. =ROUND(SUM(A1:A5),2), is called a nested function.

India's first passenger train ran from Bori Bunder (Bombay) to Thane on 16 April 1853, in present-day Maharashtra.

Andrology is the branch of medicine dealing with male health, especially reproductive and urological problems specific to men.

11/19 ≈ 0.579, 2/3 ≈ 0.667, 13/17 ≈ 0.765 and 22/7 ≈ 3.14, so the ascending order is 11/19, 2/3, 13/17, 22/7.

The product contains tan 0° = 0, so the whole product is 0.

sin θ = cos θ gives θ = 45°, so sin θ = cos θ = 1/√2. sin⁶θ + cos⁶θ = 1/8 + 1/8 = 1/4.

The Harvard Business Review's 2015 list of best-performing CEOs was topped by Lars Rebien Sørensen of Novo Nordisk.

Let the sides be x, x + 49 and x + 50. Then x² + (x + 49)² = (x + 50)², which gives x² − 2x − 99 = 0, so x = 11 cm (sides 11, 60, 61).

Sound is a mechanical wave and needs a medium (solid, liquid or gas). It cannot travel through a vacuum.

Working the clues out, the clockwise order is Varun, Tuhin, Rahul, Ujala, Qutub, Stalin, Prema, Waheeda (each person's immediate right is the one before them). Stalin is therefore on the immediate left of Qutub.

In the order Varun, Tuhin, Rahul, Ujala, Qutub, Stalin, Prema, Waheeda, the person second to the right of Ujala is Tuhin, so (Ujala, Tuhin) is the pair.

Varun sits between Waheeda and Tuhin: he is on Tuhin's immediate right and on Waheeda's immediate left, so statement C is true.

Powers of a number ending in 4 end in 6 for even powers and 4 for odd powers. 1234¹⁰² ends in 6 and 1234¹⁰³ ends in 4, so the sum ends in 0.

HOUSE: H(8)+2 = 10, O(15)−2 = 13, U(21)+2 = 23, S(19)−2 = 17, E(5)+2 = 7, alternately +2 and −2. REHEARSE: 20-3-10-3-3-16-21-3.

Art = 15, so Drama and Art only = 15 − 6 − 5 − 2 = 2. Total 30 = 2 + 3 + 6 + 2 + 2 + 5 + (Chess and Drama only), giving 10 for Chess and Drama only. Chess = 2 + 2 + 5 + 10 = 19.

From 30 = 20 + x, the number in Chess and Drama but not Art is x = 10.

Exactly one group: only Chess 2 + only Drama 3 + only Art 6 = 11.

Let one man do m and one woman w of the work per day. 4m + 3w = 1/10 and 2m + 9w = 1/8. Doubling the second, 4m + 18w = 1/4, so 15w = 3/20 and w = 1/100. Then m = (1/10 − 3/100)/4 = 7/400. 12 men do 12 × 7/400 = 21/100 = 21% a day.

Sorted: 17, 18, 24, 25, 27, 29, 42, 42, 48, 63, 65, 69, 79, 87, 98. With 15 values, the median is the 8th, 42.

A + B = 1/20, B + C = 1/50 and A + C = 1/40 of the task per day. Together A + B + C = (1/20 + 1/50 + 1/40)/2 = 19/400. So A = 19/400 − 1/50 = 11/400 and B = 19/400 − 1/40 = 9/400. Times are in the inverse ratio: A : B = 9 : 11.

All toys are books and all books are trains, so all toys are trains, which means some trains are toys.

75% correct means 25% wrong: 25% of 60 = 15 questions.
