Solution

The correct option is B 139
Arranging in ascending order : 133, 135, 137, 138, 140, 142, 148, 150

Here, number of girls = 8 which is even
Median= $\frac{1}{2} (\frac{n}{2} t h t e r m + (\frac{n}{2} + 1) t h t e r m)$
= $\frac{1}{2} (\frac{8}{2} t h t e r m + (\frac{8}{2} + 1) t h t e r m)$
= $\frac{1}{2} (4 t h t e r m + 5 t h t e r m)$
= $\frac{1}{2} (138 + 140) c m$
= $\frac{1}{2} (278) = 139 c m$
