Detailed answer is as follows

First let us calculate the water requirement per day based on the given date.

Total demand/day

Population =21000,000

Per capita demand = 300 litres/day

Total demand =21000,000 x 300

                    =6300,000,000 litres

Wastage per day

Percentage of wastage is 2%

Per day wastage in litres = (2/100) x 6300000000

                                      =126,000,000 litres

Money wasted per year

Money wasted per year =wastage per day x 360 x rate per liter

                                   =126,000,000 x 360 x 1.5

                                   =AED 68,040,000,000
