Question

a class of boys stand in a single line. one boy is nineteenth in order from both the end. how many boys are in the class​

Answer 1

There are 37 boys in the class

Explanation:

Since the boy is 19th in order from both ends,

there are 18 boys on both sides of him,

so, since they are in a line (suppose from left to right),

----18 boys on his left---the 19th boy--- 18 boys on his right----

So, in total, there are,

18 + 1 + 18 = 37 boys in the class
