33 2 % 3 -
33 1 % 3
Correct Option: D
According to question,
| Alcohol in original solution = | × 5 = 2 litres | 100 |
Water in original solution = 3 litres
On adding 1 litre water, water becomes 4 litres.
Now, 6 litres of solution contains 2 litres of alcohol.
| ∴ 100 litres of solution contains = | × 100 | 6 |
| 100 litres of solution contains = | = 33 | % alcohol. | ||
| 3 | 3 |
