Question 28

The amount of water to be mixed with 32 liters of pure fruit juice so as to get 25% profit on selling the mixture at the cost price of the pure juice, (in liters) is

Solution

Let say ,CP of 32 ltr juice is 100 Rs and x ltr water to be mixed in the juice.

Then (32+x) ltr of juices selling price is$$=\frac{100\left(32+x\right)}{32}.$$

So, $$\frac{100\left(32+x\right)}{32}=125.$$

or,$$100x+3200=4000.$$

or,$$100x=800.$$

or,$$x=8.$$

A is correct choice.
