Question

Adam’s father is 3 times as old as Adam. Two years ago, Adam was 15 years old. How old will his father be in 5 years?

Answer 1

Answer: 56 years

Explanation:

Let Adam's age be
`x` , since the father is 3 times as old as him , then the father will be
`3x`.

Two years ago

Adam =
`x - 2`

Father =
`3x - 2`

since Adam was 15 years old 2 years ago , this means that

`x-2=15`

add 2 to both sides

`x = 17`

Therefore , Adam is presently 17 years old , then the father will be 3(17) years , which means that the father is presently 51 years old.

In 5 years time , the father will be 51 + 5 years old. That is , the father will be 56 years old in 5 years time
