Question 1:
In a 70 litres mixture of milk and water, % of water is 30%. The milkman gave 20 litres of this mixture to a customer and then added 20 litres of water to the remaining mixture.What is the % of milk in the final mixture ?
A. 48%
B. 50%
Feedback 20 litre given remaining = 70-20 = 50 litre
Quantity of milk = 50*70/100 = 35 litre
Quantity of water = 50-35 = 15 litre
20 litres of water added = 50+20 = 70
=> % of milk = 35*100/70 =50%
Quantity of milk = 50*70/100 = 35 litre
Quantity of water = 50-35 = 15 litre
20 litres of water added = 50+20 = 70
=> % of milk = 35*100/70 =50%
