Question 116

In a mixture of 168 litres, the ratio of milk and water is 3:4. If this ratio is to be 3:5, then the quantity of water to be further added is. (in Litres)

Solution

Quantity of milk in 168 litres mixture = $$\frac{3}{(3+4)}\times168=72$$ litres

=> Quantity of water = $$168-72=96$$ litres

Let $$x$$ litres of water is to be added.

=> $$\frac{72}{96+x}=\frac{3}{5}$$

=> $$360=288+3x$$

=> $$3x=360-288=72$$

=> $$x=\frac{72}{3}=24$$

$$\therefore$$ Quantity of water to be further added is 24 litres.

=> Ans - (B)
