Directions: Study the following pie-charts carefully to answer these questions.

The graphs depict the following:

• Percentage of students in a college studying various subjects
• Percentage of girls out for various subjects.  Question 1: The number of girls studying Arts in college is

(a) 242
(b) 168
(c) 120
(d) 276

Question 2: For which subject is the number of boys the minimum?
(a) Law
(b) Biology
(c) Arts
(d) Maths

Question 3: For Political Science, what is the ratio of boys and girls?
(a) 4 : 3
(b) 3 : 4
(c) 2 : 3
(d) 4 : 5

Question 4: The number of girls studying Arts is what percent more than the number of boys studying Arts?
(a) 170%
(b) 150%
(c) 80%
(d) 250%

The required number = 14% of 1200 = 168.

The correct option is (b)

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)

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)
