Question

if the mean of 20,13,x,14,18,16,15,12 is 16 find the value of x

Answer 1

Solution :-

Arithmetic Mean = Sum of all observation/Total number of observations

⇒ 18 =(16 + 14 + x + 23 + 20)/5

⇒ 18 = (73 + x)/5

⇒ (x + 73) = 18*5

⇒ x + 73 = 90

⇒ x = 90 - 73

⇒ x = 17

So, the value of x is 17
