A petrol pump owner mixed leaded and unleaded petrol in such a way that the mixture contains 10% unleaded petrol. What quantity of leaded petrol should be added to 1 litre mixture so that the percentage of unleaded petrol becomes 5%?

1000 ml

900 ml

1800 ml

None of these

Explanation:

In 1 litre mixture, quantity of unleaded petrol = 100 ml

Let x ml leaded petrol be added, then 5% of (1000 + x) = 100 ml

5 (1000 + x ) = 100 × 100

⇒ x = 5000/5 = 1000 ml
