7. There are three numbers x, y and z x and y have a mean of 10
Meanstreet Task 6
There are three numbers x, y and z
x and y have a mean of 10
x and z have a mean of 12
y and z have a mean of 8
What are the three numbers?
x + y = 20
x z = 24
y + z = 16
Adding gives 2x + 2y + 2z = 60
So x + y + z = 30
So x = 14, y = 6 and z = 10
