Solution

$\begin{matrix} Number of Mangoes & Number of boxes (f_{i}) & x_{i} & f_{i} x_{i} 50 - 52 & 15 & 51 & 765 53 - 55 & 110 & 54 & 5940 56 - 58 & 135 & 57 & 7695 59 - 61 & 115 & 60 & 6900 62 - 64 & 25 & 63 & 1575 \sum f_{i} = 400 & \sum f_{i} x_{i} = 22875 \end{matrix}$
Mean of number of mangoes,
$¯ x = \frac{\sum f_{i} x_{i}}{\sum f_{i}} = \frac{22875}{400} = 57.1875$
Therefore, the required mean is $57$ . (approximately)
