    D 8 Correct Answer Incorrect Answer
    E 4.25 Correct Answer Incorrect Answer

    Solution

    Quantity of milk in 245 ml of mixture = 245 times; 10/(10 + x) Quantity of water in 245 ml of mixture = 245 times; x/(x + 10) According to question; {2450/(10 + x) + 55}/{245x/(x + 10) + 45} = 2/1 Or, 2450/(10 + x) + 55 = 490x/(x + 10) + 90 Or, (2450 ndash; 490x)/(x + 10) = 35 Or, 2450 ndash; 490x = 35x + 350 Or, 525x = 2100 Or, x = 4
