Question

The ages of three siblings combined are 22. The middle is 2 years older than the youngest and the oldest is three-times older than the youngest. What are the ages of each sibling?

Answer 1

let x be the age of youngest sibling.

x= 22- 2-x - 3x
x+3x+x = 22 - 2
5x=20
x= 20/5
x=4


now that we know the youngest sibling is 4 years old. We can calculate the middle and the oldest.

Middle: 4+2=6 years old

Oldest= 3*4=12 years old

check answer: 12+6+4
=22
