Question

The average of x y and z is 45.x is as much more than the average as y is less than the average.find the value of z

Answer 1

Answer:

45

Step-by-step explanation:

Sum of x, y and z

$\frac{x+y+z}{3}$ = 45

x+y+z = 135-------------(1)

Given that ,

x-45=45-y

x+y=90---------(2)

substituting (2) in(1)

90+z= 135

z=45
