Who can solve this great math puzzle? This is for smart people who love teasing their brains with math challenges!

## Challenge:

Jason’s age is \(\frac{5}{8}\) of Alice’s age now. In ten years, the sum of Jason’s and Alice’s age will be 72. How old will Alice be in 5 years?

**A-** 20

**B-** 30

**C-** 32

**D-** 37

**E-** 42

The correct answer is D.

Let J be the Jason’s age and A be the Alice’s age. Then:

J =\( \frac{5}{8}\) A

In 10 years: (J + 10) + (A + 10) = 72

Replace J with its value in the first equation:

Then: \((\frac{5}{8} A + 10) + (A + 10) = 72 →1 \frac{5}{8} A = 52 → A = 32\)

In 5 years, Alice will be 37. (32 + 5 = 37)
