Question

If the mean of 5 numbers is 36, what is the 5th number if four of the

numbers are 27, 42, 43, and 35?

Answer 1

33

Explanation:

To find the mean of 5 numbers, you add the 5 numbers and divide by 5.

Let the unknown number = x.

(27 + 42 + 43 + 35 + x)/5 = 36

(x + 147)/5 = 36

x + 147 = 180

x = 33

Answer: 33
