Accepted Answer

'Darkness at Noon' was written by Arthur Koestler, and 'The Sound and the Fury' by William Faulkner. Thus, statements 1 and 3 are incorrect. Statement 2 is correct.

Question 2

If (5x – y)/(5x + y) = 3/7, then what is the value of (4x2 + y2 – 4xy)/(9x2 + 16y2 + 24xy)?

Accepted Answer

Cross-multiply to get 35x - 7y = 15x + 3y, which simplifies to y = 2x. The numerator is (2x - y)^2. Substituting y = 2x gives 0, making the whole expression 0.

Question 3

___________ is a straw coloured, viscous ﬂuid constituting nearly 55 per cent of the blood.

Accepted Answer

Plasma is the pale yellow, liquid component of blood that holds the blood cells in suspension. It makes up about 55% of the body's total blood volume.

Question 4

In the following question, select the related number from the given alternatives. 65 : 82 : : 145 : ?

Accepted Answer

The pattern is n² + 1. 65 = 8² + 1, and 82 = 9² + 1. Similarly, 145 = 12² + 1, so the next number is 13² + 1 = 170.

Question 5

Accepted Answer

Total work = LCM(10,12,15) = 60 units. Efficiencies: A=6, B=5, C=4. Let total days be T. A works 2 days, B works (T-3) days, C works T days. 12 + 5(T-3) + 4T = 60. Solving gives T=7.
