Question

The sum of the ages of Ken and Erica is 62 years. 7 years ago, Ken’s age was 3 times Erica’s age. How old is Ken Now?

Answer 1

Let's say Ken's age in years is k, and Erica's is r.

We know
`k-7=3(r-7)` and
`k+r=62`.

Solving this system of equations, we get k = 43, and r = 19.

Therefore, Ken is 43 years old now.
