Some boys are sitting in a row facing north. Ganesh is 7th on the left of Akshit. Vinay, who is 20th in the row from the left, is 7th on the right of Akshit. If Kamal, who is third on the right of Ganesh, is 20th in the row from right, how many boys are there in the row?

Let's find the positions of the individuals from the left side of the row step-by-step:Vinay's position from left = $20$ Vinay is 7th on the right of Akshit.
$$\text{Akshit’s position from left}=20-7=13$$
Ganesh is 7th on the left of Akshit.
$$\text{Ganesh’s position from left}=13-7=6$$
Kamal is third on the right of Ganesh.
$$\text{Kamal’s position from left}=6+3=9$$
We are given that Kamal is 20th in the row from the right.Now we can calculate the total number of boys in the row using the formula:
$$\text{Total}=\text{Position from Left}+\text{Position from Right}-1$$
$$\text{Total}=9+20-1=28$$
There are 28 boys in the row.
