Question
There was the leakage in the refined container. If 8
litre of refined is leaked out per day then it would have lasted for 20 days and if the leakage was 12 litre per day, then it would have lasted for only 16 days. For how many days would the refined have lasted if there is no leakage and it was completely used for consumption?Solution
Let x kg of Refined is used for daily consumption, then (x + 8) × 20 = (x + 12) × 16 20x + 160 = 16x + 192 4x = 32 x = 8 ∴ Total quantity of Oil = (8 + 8) × 20 = 320 litre Required number of Days = 320/8 = 40 days
