Correct Answer: $2 \cos ^2 {B}-1$

Solution : $(\cot B-\tan B)\sin B\cos B$
= $(\frac{\cos B}{\sin B}-\frac{\sin B}{\cos B})\sin B\cos B$
= $(\frac{\cos^2 B - \sin^2 B}{\sin B\cos B})\sin B\cos B$
= $\cos^2 B - \sin^2 B$
= $\cos^2 B - (1- \cos^2 B)$
= $2\cos^2 B - 1$
Hence,

Correct Answer: 0

Solution : The number 3*7440 is divisible by 12, so we can say the number is also divisible by both 4 and 3.

Solution : Let the total number of boys be x.
The amount contributed by each boy = Total number of boys
According to the question,
x² = 12544

So, the number of boys = 112
Hence, the correct answer is

Correct Answer: 15 : 22

Solution : $\small\text{Cost Price} = \text{Selling Price} × \frac{100}{100\ ±\ \text{Loss or Profit%}}$
We get, Cost price for A $= 5400 × \frac{100}{110}=\frac{54000}{11}$
And, Cost price for B $= 5400 × \frac{100}{75}=1800 × 4$
$\therefore$ Ratio of both CP $= \frac{54000}{11} : 1800 × 4$
