You have 5 jars of pills. Each pill weighs 10 gram, except
for contaminated pills contained in one jar, where each pill
weighs 9 gm. Given a scale, how could you tell which jar had
the contaminated pills in just one measurement?
Answer Posted / jes
Take 1 pill from 1st jar,2 pills from 2nd jar,3 pills from 3rd jar,4 pills from 4th jar and 5 pills from the 5th jar.put all the pills together.since each pill weighs 10gram,totally we have taken 15 pills(1+2+3+4+5=15).so it weighs 150( if not contaminated).but definitely there is a cintaminated jar.if it weights 149 then 1st jar is contaminated,if 148 then 2nd jar is the contaminated jar,147 means 3rd jar,146 means 4th jar,145 means 5th jar.
