INITIAL CONCENTRATION = 125 LITRES

REPLACED CONCENTRATION = 25 LITRES

FINAL CONCENTRATION = INITIAL (1- REPLACED/INITIAL)^3                  [AS THIS METHOD WAS DONE FOR 3 TIMES]

= 125 ( 1 - 25/125)^3

= 125 ( 100/125)^3

ON SOLVING THIS YOU WILL GET   64 LITRES......WHICH IS MILK

AND REMAINING   61 LITRES WILL BE WATER .
