Question
A mixture contains alcohol and water in the ratio 4 : 3. If 5 litres of water is added to the mixture, the ratio becomes 4: 5. Find the quantity of alcohol in the given mixture?
Answer: Option A
- Let the quantity of alcohol and water be 4x litres and 3x litres respectively
4x/(3x+5)=4/5
20x=4(3x+5)
8x=20
x=2.5
Quantity of alcohol = (4 x 2.5) litres = 10 litres
