Sonu is fifteenth from the front in a column of boys. There were thrice as many behind him as there were in front. How many boys are there between Sonu and the seventh boy from the end of the column ?

Options

A. 33
B. 34
C. 35
D. Data inadequate

Answer

C

Explanation

Number of boys in front of Sonu = 14. Number of boys behind Sonu = (14 * 3) = 42. So, Total number of boys in the column = (14 + 1 + 42) = 57. In a column of 57 boys, the seventh boy from the end is clearly 51st from the start. Thus, we have to find the number of boys between the 15th and the 51st boy, which is clearly 35th.
