Solution

Step1: Given data
The distance between Raj and his image is 100cm

Raj's distance from the mirror is x

Step 2: To find

The value of x

Step 3: Explanation

We know, for a plane mirror, the distance between the object and mirror is equal to the distance between the image and the mirror.

Given, Raj's distance from the mirror is x, so, the distance between Raj and the image will be 2x

It is also given that, the distance between Raj and the image is 100cm

Therefore,

2x=100cmx=1002cmx=50cm

Hence, the possible value of x is 50cm.
