Answer 1

Given :  in a row of boys and girls Radha is sixth from the top and Atul is twelfth from top. Radha is fourth  from the top and sixth from bottom among girls, Atul is seventh from the top and twenty fourth  from bottom among boys.

To Find : How many children are there in the row?​

Solution

Radha is 6th from top

hence 5 (boys + girls above Radha)

Atul is twelfth from top

hence  11 (boys + girls above Atul)

Radha is fourth  from the top and sixth from bottom among girls

3 girls above radha  and 6 girls below radha

Hence Total girls = 3 + Radha + 6  = 10  Girls

Atul is seventh from the top and twenty fourth  from bottom among boys.

6 boys above atul   and 23 boys  below atul

Hence Total boys = 6 + Atul + 23 = 30  Boys

10 Girls + 30 Boys = 40

40 children are there in the row
