Question

Find capacity of fuel tank?

Answer 1

1/5th=20%
3/4th=75%

So We add 22 litres of fuel to bought the filled capacity of fuel from 20% to 75%
So, means We add 55% fuel in the tank!
So, 55%=22 Litres
1%= 22/55 Litres
100% (Capacity of fuel)= 22/55 * 100
=40

So, Here The Capacity of Fuel is 40 Litres!

Hope it helps!
