Answer: A) 65
Explanation: The given number series is 8, 14, 24, 40, ? .
It follows a pattern that,
8
8 x 1.5 + 2 = 14
14 x 1.5 + 3 = 24
24 x 1.5 + 4 = 40
40 x 1.5 + 5 = 65
Hence, the next number in the given number series is 65.
Since Nithya and Suganya exchange places, so Rita’s new position is the same as Monika’s earlier position. This position is 17th from the right and 10th from the left. Therefore Number of girls in the row = (16 + 1 + 9) = 26.
