# A residential

A residential colony has a population of 5400 and 60 litres of water is required per person per day. For the effective utilization of rain water, they constructed a water reservoir measuring 48m × 27m × 25m to collect the rain water. For how many days, the water of this tank is sufficient, if during rain the height of water level is 5 m?

Result

d1 =  100 d
d2 =  20 d
