ANSWERS with Hints :-
1. a
2. b
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
Only English 24 60
Only Sanskrit 36 36
Both subjects 40 24
100 120
3. c

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)
