In a class of 180, where girls are twice the number of boys, Rupesh[a boy] ranked 34th from the top. If there are 18 girls ahead of Rupesh, how many boys are after him in rank?
A) 45
B) 44
C) 60
D) can't be determined
Answer: B) 44
Explanation:
No. of boys up to the 34th rank = 34-18 = 16
Total no of boys = 180x1/2+1 = 60
number of boys after the rank of Rupesh = 60 - 16 = 44
