Answers and Explanations

Answer 1: (b)

The required number = 14% of 1200 = 168.

The correct option is (b)

Answer 2: (a)

In Law, the number of boys = 20% of 1800 – 30% of 1200 = 360 –360 = 0.

Thus, the number of boys in law is least.

The correct option is (a)

Answer 3: (b)

The required ratio is

= {(35% of 1800 – 30% of 1200)/(30% of the 1200)}

= ((630 -360)/360}

=27/36 = 3:4

The correct option is (b)

Answer 4: (d)

Number of girls studying arts = 14% of 1200 = 168

Number of boys studying arts = 12% of 1800 -168 = 216-168 = 48

The required percentage = {(168 – 48)/48} x 100 = 120/48 x 100 = 250%
