Question

In a class of 60 students, where the number of is twice that of boys, Kamal, a boy, ranked seventeenth from the top. If there are 9 ahead of Kamal, the number of boys in rank after him is:
(a) 13

(b) 12

(c) 7

(d) 3

Answer 1

(b) Let the number of boys be x, then numbers of ***** = 2x

x + 2x = 60; or 3x = 60; or x = 20
So numbers of boys = 20 and numbers of ***** = 40

Numbers of student behind Kamal in rank = (60 – 17) = 43

Numbers of ***** ahead of Kamal in rank = 9
Numbers of boys behind Kamal in rank = (43 – 31) = 12
