Explanation:

- Initially, Sunil is 20th from the left and Deepak is 36th from the right.

- After they switch places, Sunil becomes 28th from the left.

- This means Deepak's new position from the left must be Sunil's initial position, which is 20th.

- Now we have two important details:

- Sunil's original position is 20th from the left.

- Deepak's new position is 20th from the left.

- The total number of boys is the sum of Sunil’s new position from the left (28) and Deepak’s position from the right (36) minus 1, because their positions overlap at the point of switching.

\( \text{Total boys} = 28 + 36 - 1 = 63 \)

- Option 2: 63 is the correct answer.
