18 litres of Petrol was added to a vessel containing 80 litres of Kerosene. 49 litres of the resultant mixture was taken out and some more quantity of petrol and kerosene was added to the vessel in the ratio 2:1. If the respective ratio of kerosene and petrol in the vessel was 4:1, what was the quantity of kerosene added in the vessel?

1 litre

2 litre

5 litre

4 litre

Explanation:

Total quantity of the mixture = 18+80 = 98 litre
quantity of petrol remaining = 18/2 = 9
quantity of kerosene remaining = 80/2 = 40
(40 + 2x) / (9 + x) = 4 / 1
x = 2
Quantity of kerosene added in the vessel = 2x = 4 litre
