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?

Read Solution (Total 2)

Take 1 pill from jar 1, 2 pills from jar 2, 3 pills from jar 3, 4 pills from jar 4 and 5 pills from jar 5. Find total weight. Since one jar contains pills of 9 grams, total weight will be less than 150 gram.

If total weight = 149 gram, jar 1 contains contaminated pills.
If total weight = 148 gram, jar 2 contains contaminated pills.
If total weight = 147 gram, jar 3 contains contaminated pills.
If total weight = 146 gram, jar 4 contains contaminated pills.
If total weight = 145 gram, jar 5 contains contaminated pills.
