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

Step-by-step 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
