Question

In a marriage, a 30-liter milkshake mixture of juice and milk contains 5% milk. How much milk must be added to make 10% milk in the mixture?

  • 2
  • 1.8
  • 3
  • 2.6
Answer- B

The mixture has 5% milk, so the juice would be 95% of 30 litres.

Juice = 95/100 * 30 = 28.5 liters

Milk = 30 - 28.5 = 2.5 liters

Let Milk to be added = x liters

Now, 2.5+x/30+x * 100 = 10

2.5+x/30+x = 1/10

25 + 10x = 30+x

5 = 9x

x = 1.8 liters
