Hey Vikas! We Know That, Mean = Sum of all numbers/2 Let sum of all numbers be x. => x / 16 = 8 => x = 8*16 = 128 Now, we add 2 to each number. Since there are 16 numbers, the increase in sum will be 16*2 = 32: => New Mean: => x + 32 / 16 => 128 + 32 / 16 => 160 / 16 => 10 Thus, the new mean is 10.
