Solution

The correct option is B
17

$\begin{matrix} C l a s s I n t e r v a l & F r e q u e n c y & C u m u l a t i v e F r e q u e n c y 30 & 12 & 360 40 & 16 & 640 50 & p & 50 p 60 & 15 & 900 70 & 8 & 560 80 & 19 & 1520 90 & 13 & 1170 T o t a l & 83 + p & 5150 + 50 p \end{matrix}$

$\sum f_{i} = 83 + p$

$\sum f_{i} x_{i} = 5150 + 50 p$

$\frac{5150 + 50 p}{83 + p} = 60$

$5150 + 50 p = 4980 + 60 p$

$170 = 10 p$

$p = 17$
