Question

Hi, need help on thus qns.

Ali is 1/5 as old as his uncle now. In 8 years’ time, he will be 1/3 as old as his uncle. How old is Ali now?

 

Tks.

 

Answer

Now —
Ali : 1 unit
His uncle : 5 units

In 8 years’ time —
Ali : 1 unit + 8
His uncle : 5 units + 8

(1 unit + 8) x 3 = 3 units + 24 = 5 units + 8
1 unit = (24 – 8)/(5 – 3) = 8

Ans : 8 years old.

Ali = 1 Unit

Uncle = 5 Unit

3(1 U +8) = 5 U +8

3U + 24 = 5U + 8

2U = 16

Ali = 8 years old
