Eight years from now, Diya's age will be five-thirds of her age four years ago. What is her present age?

Explanation

1. 01

   Let her present age be $x$: $x + 8 = \frac{5}{3}(x - 4)$.

2. 02

   Multiply by 3: $3x + 24 = 5x - 20$.

3. 03

   $2x = 44$, so $x = 22$. Check: $30 = \frac{5}{3} \times 18$.
