Question

The average of three numbers is 30. The first is twice of second and second is one-third of third number. find the numbers.

Answer 1

let third no. be x

second no. = 1/3x

first no. = 2×1/3x

= 2/3x

avg. = 30 = x+1/3x+2/3x ÷ 3

6x/3 ÷ 3 = 30

6x/3 = 90

6x =. 270

x. = 45

third no. = 45

second no. = 1/3×45

= 15

first no. = 15×2

= 30
