Question

The ratio between the present age P and Q is 3:4 respectively. If Q is 20 years what will be the ratio of the ages after 5 years

Answer 1

Ratio will be the same

example you are 10 years younger than your brother after 20 years also you will be younger

Answer 2

Hi friend!
Let's see,

Ratio
$= 3:4 \\ = 3x:4x \\ \\ 4x = 20 \\ x = \frac{20}{4} \\ x = 5 \\ \\ 3x = 3 \times 5 = 15 \: years \: old \\ 4x = 4 \times 5 = 20 \: years \: old$

5 years later:
$P = 15 + 5 \: years \: old = 20 \: years \: old \\ Q = 20 + 5 \: years \: old = 25 \: years \: old$

Ratio = 20:25
= 4:5

Therefore, the ratio between ages of P & Q after 5 years will be 4:5.
