Answer» The cost of water charged per litre is Rs. 0.1 per litre and the monthly bill for each flat is Rs. 1728; ∴ The total amount of water consumed by each flat in whole month = 1612.8/0.1 = 16128 litres ∴ Rate of use of water per hour by each flat in FEBRUARY = 16128/[24 × 28] = 24 litres/hr Since all the FLATS are occupied in February; ∴ Number of hours in which the tank will GET emptied = 60000/[40 × 24] = 62.5 hours ∴ D = 62.5 |
