Initial Setup
- The container starts with 120 litres of petrol.
Step 1: First Replacement
- 20 litres of petrol is removed from the container.
- Remaining petrol: 120 - 20 = 100 litres of petrol.
- 40 litres of kerosene is added.
- Now, the mixture contains 100 litres of petrol and 40 litres of kerosene.
Step 2: Second Replacement
- Calculate the total volume after the first step: 100 + 40 = 140 litres.
- When 40 litres of the mixture is taken out, the ratio of petrol to kerosene is 100:40 or 5:2.
- Amount of petrol in 40 litres taken out:
- Petrol in 40 litres = (5/7) * 40 = 28.57 litres (approximately).
- Amount of kerosene in 40 litres taken out:
- Kerosene in 40 litres = (2/7) * 40 = 11.43 litres (approximately).
- Remaining petrol after removal:
- Petrol left = 100 - 28.57 = 71.43 litres (approximately).
- Remaining kerosene after removal:
- Kerosene left = 40 - 11.43 = 28.57 litres (approximately).
- Add 60 litres of kerosene:
- New kerosene total = 28.57 + 60 = 88.57 litres (approximately).
Final Calculation
- Final amounts:
- Petrol: 71.43 litres
- Kerosene: 88.57 litres
Ratio of Petrol to Kerosene
- Ratio = 71.43:88.57.
- Simplifying gives approximately 25:31.
Thus, the final ratio of petrol to kerosene is 25:31, matching option 'A'.
