Question : Directions: Sunil's position from the left in a row of boys is 20th, and Deepak's position from the right is 36th. After changing positions, Sunil becomes 28th from the left. How many boys are there in the row?
Option 1: 52
Option 2: 63
Option 3: 59
Option 4: 48
Correct Answer: 63
Solution :
Given:
Sunil's position from left = 20th
Deepak's position from right = 36th
After interchanging their positions, Sunil's position from left = 28, and Sunil's position from right = 36
So, the total number of boys in a row = Sunil's position from left + Sunil's position from right – 1
The total number of boys in a row = 28 + 36 – 1
= 64 – 1
= 63
So, there are a total of 63 boys in a row. Hence, the second option is correct.
