Question

Three even numbers sum up to 162. the smallest is half the largest and the middle number is 3/4 the largest. what are the three numbers? enter as a comma separated list.

Answer 1

Lets name the largest number as x 
smallest number is half the largest , therefore its x/2 = 0.5x
then middle number is 3/4 the largest , therefore its 3/4x = 0.75x
the sum of the three numbers are 162
the three numbers added are 
x + 0.5x + 0.75x = 162
2.25 x = 162
x = 72
the largest number is 72
then middle number 0.75 x = 0.75 x 72 = 54
smallest number is 0.5x = 0.5 x 72 = 36
answer is  -   36,54,72
