Answered by vanshikaaax

Given, there are 16 numbers
Mean = 8.Let their sum be x.
So mean = x/16 =8.
If two is added to each number then the sum increases by 16*2 = 32.So, for finding the new mean we'll divide it by 16
∴ Mean = (x+32)/16 ⇒ 8+2 =10.

So, the required new mean is 10.
Hope it helps u !
