Correct Answer: 19


Solution : Dipika's position = 11th from the West end.

Sudesh's position = 15th from the East end.

After interchanging their positions,

Sudesh's current position = 9th from the East end.

So, the total number of persons in the row = Dipika's position + Sudesh's current position – 1 = 11 + 9 – 1

Therefore, the total number of persons in the row = 20 –1 = 19 .

Hence, the second option is correct.
