Question 23

In a mixture of 50 liters, milk and water are in the ratio of 3:2. How much water should be added to make the ratio of the two equal?

Solution

In a mixture of 50 liters, milk and water are in the ratio of 3:2.

Quantitiy of milk = $$\frac{3}{5}\times 50 = 30$$

Quantitiy of water = $$\frac{2}{5}\times 20 = 20$$

To make the mixture equal, let x be water added

$$\frac{30}{20+x}= \frac{1}{1}$$

$$30=20+x$$

$$x = 10 ltrs$$

Option C is correct.
