Question

In 80 liters mixture of milk and water the ratio of amount of milk to that of amount of water is 7:3 .in order to make this ratio 2:1. How many liters of water should be added

Answer 1

Answer:

water added =2.6 litres

milk substracted =2.7

Step-by-step explanation:

80lit mixture of milk and water with ratio =7:3

milk =80*7/10=56 litters

water= 80*3/10=24 litters

to make a ratio of 2:1 in 80liters

milk =80*2/3=26.6*2=53.3 litre

water =80*1/3=26.6 litre

water should be added 26.6-24=2.6 litres

and milk should be substracted =56-53.3=2.7 litres
