    TYPE 7

    A container has only two types (P and Q) of oil in the

    ratio 3:2 respectively. When 80 litre of oil Q is added to the  container the quantity of oil P becomes 25% of that of oil Q. Find the capacity of the  container if it becomes full after addition of 80 litre of oil.
    A 120 litres Correct Answer Incorrect Answer
    B 145 litres Correct Answer Incorrect Answer
    C 150 litres Correct Answer Incorrect Answer
    D 116 litres Correct Answer Incorrect Answer
    E 135 litres Correct Answer Incorrect Answer

    Solution

    Let the quantity of oil in the container be 3x and 2x litres respectively. According to the question, => 3x = 0.25 × (2x + 80) => 2.5x = 20 => x = 8 Total capacity of the container = 3x + 2x + 80 = 120 litres.
