In a class, boys stand in a single line. One of the boys is nineteenth in order from both the ends. How many boys are there in the class?

Options

A. (a) 27
B. (b) 37
C. (c) 38
D. (d) 39

Explanation

Clearly ,number of boys in the row
= (18 + 18 + 1) = 37
The question can be solved by formula also. Total number of persons in a row or class = (Rank of a person from upper end or left end) + (Rank of that person from lower or right end) - 1 (because that
particular place counts two times)
Total number of boys in the class = 19 + 19 - 1
`=37`
