A container of 64 liters was full of milk. 16liters liquid was drawn off and replaced by water and this process was repeated two times more. Find quantity of water in the mixture now.

37 liters

\(\frac{16}{64}\) = \(\frac{1}{4}\) in which 4 is original quantity and 1 is replaced water

Note- we have to perform the operation n number of times given below=

Where n = 3 (number of times solution to be replaced.)

Original quantity             Remaining  milk

4                                  3

4                                  3

4                                  3

———————————————

64 (original quantity)      27 ( Remaining milk)

Quantity of water in the mixture now = 64 - 27 = 37
