Question

the mean median and mode of four numbers is 8 the smallest number is 7 find the numbers

Answer 1

The smallest number is 7.
Mode is 8. This means 8 comes at least two times in four numbers.
Let the fourth number be x.

So, we have numbers as 7, 8, 8 and x.
Mean of these numbers = (7 + 8 + 8 + x)/4 = 8

(23 + x)/4 = 8

23 + x = 32

x = 32 - 23

x = 9

hence, the number is 7,8,8,9.
