Answer: Option C — 44
Detailed Solution
After interchanging, Mohan takes Sohan's original position.
Mohan is now 25th from the left → Sohan's original position is 25th from the left.
Sohan is 20th from the right → Total = 25 + 20 − 1 = 44.
✓ Check
Sohan's original position from left = 44 − 20 + 1 = 25 ✓. After swap, Mohan is at position 25 from left ✓.Answer: 44 students are in the row.
Quick tip
After swap, Mohan = Sohan's old position = 25th from left. Total = 25 + 20 − 1 = 44.
