Question

Wine and water ration 7:5and the mixture is drawn off 9 litre and add 9litre water then the ratio of wine and water 7:9 what is initial quantity of wine

Answer 1

Answer:

36.75 L

Let initial amount of milk,m=x L

water, w=5x/7 L

If 9 L is taken out, now

m’=x-9*7/12

w’=5x/7–9*5/12

Adding 9 L w into the mixture

w”=5x/7–9*5/12+9

Now the mixture has same amount of w and m

So equating m’=w”

We get initial amount of milk= 36.75 L
