60 litres.
ReplyDeleteCorrect Answer is 40 Liters
ReplyDeleteExlanation :
20% of 120 Liters is 24 Liters Water is already available in the mixture
Now we have to increase it to 40% in new solution
So,
40%(120+x)=24+x
Calculate the Value of x you will find the right answer 40
or you can use the method of Mixture and Allegation
