Question

Five whole numbers are written in order.
4 6 x y 10
The mean and median of the five numbers are the same.
Work out the values of x and y.​

Answer 1

Answer:

mean = median

$\frac{4 + 6 + x + y + 10}{5} = x$

$\frac{20 + x + y}{5} = x$

x + y + 20 = 5x

y + 20 = 4x

y = 4x-20

x = 7 , y = 8

As 6<x , y >10
