Question 1:
In a class of 60, where girls are twice that of boys, Kamal ranked seventeenth from the top. If there are 9 girls ahead of Kamal,how many boys are after him in rank ?
A. 3
B. 7
C. 12
Feedback Let the number of boys be x. Then, number of girls = 2x.
x + 2x = 60 or 3x = 60 or x = 20.
So, number of boys = 20 and number of girls = 40.
Number of students behind Kamal in rank = (60 - 17) = 43.
Number of girls ahead of Kamal in rank = 9.
Number of girls behind kamal in rank = 40 - 9 = 31.
Number of boys behind Kamal in rank = 43 - 31 = 12.
x + 2x = 60 or 3x = 60 or x = 20.
So, number of boys = 20 and number of girls = 40.
Number of students behind Kamal in rank = (60 - 17) = 43.
Number of girls ahead of Kamal in rank = 9.
Number of girls behind kamal in rank = 40 - 9 = 31.
Number of boys behind Kamal in rank = 43 - 31 = 12.
D. 23
