Water used by total population in a day = 1500 * 120
                                                               = 180000 l

Water in the tank = 20*15*6 m3
                            =1800 m3
                            =1800*1000 l
                            =1800000 l
 
 let number of days be y

y * water used by whole in 1 day = total volume of water
y*180000 = 1800000
y = 1800000 / 180000
y = 10
the water will last for 10 days

It is not advisable to drink stagnant water of the tank after 5 days
