Quantitative Aptitude Test Question 10


(567/(162+x) = 1 1128=162+x )
729 ml of a mixture contains milk and water in ratio 7:2. How much of the water is to be added to get a new mixture containing half milk and half water?

total mixture is 729.
it has 7x part milk and 2x part water
i.e 7x+2x=729 x=81
Milk is 7*81=567 . Water is 81*2=168
suppose after adding y quantity of water their ratio become equal. i.e both become equal in quantity.

567/(168+y) = 1/1

567 = 168+y
567 - 168 = y
y=399

Wrong Calculation Above

This is a wrong calculation. 81*2=162 nd not 168. Therefore your answer is coming wrong. It should be 405.
567/(162+x)=1
x=567-162=405
