Question
There was the leakage in the Oil container. If 10 litre
of oil is leaked out per day then it would have lasted for 25 days and if the leakage was 16 litre per day, then it would have lasted for only 20 days. For how many days would the petrol have lasted if there is no leakage and it was completely used for consumption?Solution
Let x kg of Petrol is used for daily consumption, then (x + 10) × 25 = (x + 16) × 20 25x + 250 = 20x + 320 5x = 70 x = 14 ∴ Total quantity of Oil = (14 + 10) × 25 = 600 litre Required number of Days = 600/14 =300/7 days
