Answer 1

The logic followed here is:

Given that:-

In a row of girls, Mahua is 7th from one extreme end.

In a row of girls, Mahua is 11th from other extreme ends.

Total number of girls in the row = Mahua position from one end + Mahua position from other end - 1 (Because Mahua added two times.)

Total number of girls in the row = 7 + 11 - 1 = 18 - 1 = 17.

Hence, "option 1" is the correct answer.
