Answer Posted / krishna prabhu
taking 1 pills from 1st container
2 pills from 2nd container
3 pills from 3rd container
4 pills from 4th container
and 5 pills from 5th container
eg:
if 3rd container has contaminated pills, we have taken 3 pills from 3rd container,
then 3rd container has 3*9=27 grams of pills
remaining containers will have,(1*10)+(2*10)+(3*9)+(4*10)+(5*10)=147
if there is no contaminated pills in each jar then total weight is 150,so 150-147=3
3rd container contains contaminated pills
