The number of women in 1991 was:
Option 1: 57,630
Option 2: 56,740
Option 3: 52297
Option 4: 62,957
Correct Answer: 57,630
Solution : Total population in 1991 = 1,53,922 – 5,337 = 1,48,585 The number of women in 1991 = 1,48,585 – 69,395 – 21,560 = 57,630 Hence, the correct answer is 57,630.

Question : The value of $\frac{\sin\theta-2\sin^{3}\theta}{2\cos^{3}\theta-\cos\theta}$ is equal to:
Option 1: $\sin\theta$
Option 2: $\cos\theta$
Option 3: $\tan\theta$
Option 4: $\cot\theta$
Correct Answer: $\tan\theta$
Solution : Given: $\frac{\sin\theta–2\sin^{3}\theta}{2\cos^{3}\theta–\cos\theta}$ $=\frac{\sin\theta(1–2\sin^{2}\theta)}{\cos\theta(2\cos^{2}\theta–1)}$ We know that $\cos2\theta=1-2\sin^{2}\theta=2\cos^{2}\theta-1$ So, $\frac{\sin\theta(\cos2\theta)}{\cos\theta(\cos2\theta)}$ $=\frac{\sin\theta}{\cos\theta}$ $=\tan\theta$ Hence, the correct answer is $\tan\theta$.
Question : Directions: If 20 June of a particular year falls on the 6th day after Tuesday, then what will be the day on 11 August of the same year?

Option 2: 40
Option 3: 45
Option 4: 30
Correct Answer: 35
Solution : Given: 6 : 42 :: 5 : ?
Here, multiply the first number by 7 to get the second number of each pair. Like, 6 : 42→6 × 7 = 42 Similarly, for 5 : ?→5 × 7 = 35
So, 5 is related to
