Answer 1

9.tablets = 250000
   weight of one tablet =20 mg
   weight of the whole tablets 250000*20=50,00,000mg=>5000gram=>5 kg


15.for 850 litres = one minute
     for 1377000 litres =13,77,000/850=1620 minutes=>27 hours
                            

Answer 2

9)-First we will convert 20mg into gram and kg as mentioned in the question.
20mg=20/1000=1/50=0.02g and for kg=0.02/1000=2/100000=1/50000=0.00002kg
now we will multiply these values which we have got by the no. of tablets i.e.250000=250000×0.02=5000g and 250000×0.00002=5kg
15)-time taken=1 min=1/60hr=0.0167hr(approx) water filled =850L
time taken to fill1377000L=1377000/85=1620min.=1620/60hr=27hours
Hope it helps!^_^
