Q11. Two numbers are in the ratio 5:6 and if 4 is subtracted from each, they are reduced to 2:3, then the highest number is
(a) 4 (b) 12 (c) 8  (d) 10

Q12. A square and a triangle have equal areas. If the ratio side of square and the height of triangle is 2/3 find the ratio of base to height. (a) 2/3 b) 4/3 (c) 4/5 (d) 9/8 (e) None of these

Ans. As the problem a2 = 1/2h × b
a/h= 2/3 or a = 2/3h
h = 3/2 b
From equation (i) ½ h b = a2
½ h b = (2/3h)2 = 4/9h2 or h/b = 1/2/4/9 = ½ × 9/4 = 9/8

Q13. How many prime numbers lie between 115 – 122.
(a) 2 (c) 4 (e) 6
(b) 3 (d) 5

Ans. 115, 116, 117, 118, 119, 120, 121, 122.

(b) 10 years (d) 5 years
(e) None of these

Ans. (b) 10 years
Sol: Suppose Shyam’s age = x So Ram’s age = 5x
As per the problem 5x – x = 8 or 4x = 8 or x = 2 So Ram’s age = 5x = 5 × 2 = 10 years
