Hi!

_______________________________________

Given :

50 Numbers

Let x be the mean of 50 numbers

Sum of 50 numbers => 50 x

According to Question :

Each number is Subtracted from 53

$\frac{53 *50 - 50x }{50} = -3.5$

Solving Further :

=> 2650 - 50x = -175

=> 50x = 2650 + 175

=> 50x = 2825

=> $x = \frac{2825}{50}$

=> 56.5

Therefore , option (D) is correct
