    There was a certain leakage x in the petrol tank. If 5

    litre of petrol more from x is leaked out per day then it would have lasted for 30 days. If the leakage was 7 litre of petrol per day from x, then it would have lasted for only 24 days. For how many days would the petrol have lasted, if there is no leakage and it was completely used for the vehicle?
    A 120 days Correct Answer Incorrect Answer
    B 90 days Correct Answer Incorrect Answer
    C 80 days Correct Answer Incorrect Answer
    D 60days Correct Answer Incorrect Answer

    Solution

    Let x litre of petrol is used for transport purpose daily Then (x + 5) × 30 = (x + 7) × 24 30 x + 150 = 24 x + 168 6 x = 18 x = 3 Therefore, total quantity of oil = (3 + 5) × 30 = 240 litre Required number of days = 240/3 = 80days
