There are 55 boys sitting in a row and facing North. Suraj is sitting $24\text{th}$ from the left end and he is $4\text{th}$ to the right of Abhay. What is the position of Abhay from the right end in the row ?

1. Total number of boys in the row = $55$
2. Position of Suraj from the left end = $24\text{th}$
3. Suraj is $4\text{th}$ to the right of Abhay, which means Abhay is located to the left of Suraj.

$$\text{Position of Abhay from the left end}=24-4=20\text{th}$$

4. To find Abhay's position from the right end, use the formula:

$$\text{Position from right end}=\text{Total boys}-\text{Position from left end}+1$$

$$\text{Position of Abhay from right end}=55-20+1=35+1=36\text{th}$$
