There are 50 numbers. Each number is subtracted from 53 and the mean of the number so obtained is found to be `-3.5`. The mean of the given number is

Options

A. 46.5
B. 49.5
C. 53.5
D. 56.5

Explanation

To find the mean of the given numbers, we can follow these steps:

### Step 1: Understand the problem
We have 50 numbers, and when each number is subtracted from 53, the mean of the resulting numbers is -3.5. We need to find the mean of the original 50 numbers.

### Step 2: Set up the equation
Let the original numbers be \( x_1, x_2, x_3, \ldots, x_{50} \). The mean of the numbers obtained after subtracting each from 53 can be expressed as:
