boys and Vivek is 18th from the right end. Gagan is 11th from Aman towards the right and 3rd from Vivek towards the right end. How many boys are there in the row?Solution
Vivek is 18th from the right end and Gagan is third to the right of Vivek. So, Gagan is 15th from the right end. Thus there are 15 boys to the left of Aman; 10 boys between Aman and Gagan ; and 14 boys to the right of Gagan. So, number of boys in the row = 15 + 1 + 10 + 1 + 14 = 41
