In a row of $24$ boys, Vijay is $15\text{th}$ from the right end. Vinay is $5\text{th}$ to the left of Vijay. What is Vinay’s position from the left end of the row?

1. Total boys in the row $=24$
2. Vijay's position from the right end $=15\text{th}$
3. Vinay is $5\text{th}$ to the left of Vijay, so Vinay's position from the right end $=15+5=20\text{th}$ from the right end.

Now, calculate Vinay's position from the left end:

$$\text{Position from Left}=\text{Total}-\text{Position from Right}+1$$

$$\text{Position from Left}=24-20+1=4+1=5\text{th}$$
