For Q. 3 to 5

From (1) Students in section A

=5 x 220=100

11

Students in section B = 120

From (3) Students studying only Sanskrit from section A

=30% of 120=36

»60% of students studying only English in section B=36

»Students studying only English in section B

= 36x100 =60

60

From (2) Number of students studying only English from section A = Number of students studying both Sanskrit & English from section B

= 40% of 60=24

Hence

Subject Section A Section B

8. a, b & c all are correct.

(Let M be the age of Sangita & N be her son’s present age.

a. (M - 5) = 2(N - 5)

»M = 2N – 10 + 5 = 2N – 5

M+5 = 12

N+5 7

Solving we get M = 55, N = 30

b.M = 11 or 6M = 11M

N 6

M+5 = 12

N+5 7

Solving we get M = 55, N = 30

c. (M – 5) = 2(N – 5)

M = 11

N 6

Solving we get M = 55, N = 30)
