In a row, Meena is 9th from the left. When she exchanges her place with Nita, who stands 5 places to her right, Meena becomes 18th from the right. How many persons are there in the row?

Correct answer: B

Explanation

Nita stands at 9 + 5 = 14th from the left, so Meena's new place is 14th from the left and 18th from the right; total = 14 + 18 − 1 = 31.
