In a row of boys, Rahul is 19th from top and Ajay is 21st from bottom. They interchange their position. Ajay now becomes 28th from bottom. How many total boys are there in the row? Correct Answer 46

Rahul is 19th from the top and Ajay is 21st from the bottom.

so, there are 18 students ahead of Rahul and 20 are behind Ajay.

Now after interchanging their position

Ajay becomes 28th from the bottom therefore, there must be 27 students behind him and 18 students ahead of him (as he is at Rahul's earlier position).

So, Total students = 18 + 27 + 1 = 46.

Hence, total 46 boys are there in the row.
