Question

The average of three numbers is 16 if one of the numbers is 18 what is the sum of the other two numbers

Answer 1

sum of two numbers is 30

Explanation:

let three numbers are x,y,z

average =x+y+z/3

x+y+z/3=16

x+y+z=48......(1)

The sum of two numbers is 18.

according to condition:

let x=18

subtitute x=18 in (1)

18+y+z=48

y+z=48-18

y+z=30
