    E 160 Correct Answer Incorrect Answer

    Solution

    Since quantity of milk in mixture a. Is X - 100 liters more than that of water in it Therefore. Quantity of milk in mixture A = {(X + 140 + X – 100)/2} = X + 20 liters. Quantity of water in In the mixture A = (X + 140) - (X + 20.) = X + 140 - X -20 = 120 Final quantity of water in can P = 0.75 *120+(x-90) = 90+x-90 = x litres. Final quantity of milk In can P = 0.75* (x+20)= 0.75x+15+50= 0.75x+65 lt. As per the question  {x/(0.75x+65)}=9/10 X=180
