Vinay Sipani    10 years AGO

Ratio of juice and milk = 4/3
Let there be 4x lts of juice and 3x lts of water.

Now,7l water is added => (3x+7) lts water.

Ratio = 3/4 = 4x/(3x+7)
=> x = 3

Therefore, quantity of juice present = 4x = 12 lts.

Sanu Panji   10 years AGO

1st ratio = 4:3= 12:9
2nd ratio= 3:4= 12:16
(since juice remain same we change the 2nd ratio such that juice become same in both ratio)
7 litre of water is added
so the quantity of juice in the mixture= 12*7/(16-9)
=12 litre

4x/3x if 7 Litres is water is added means 4x/(3x+7) so the Ouput is 3/4.

So 4x/(3x+7)=3/4 ==>Cross Multiply==> 16x=9x+21

So x=3.

The juice contains (4*x). So the Answer is 12 Litres
