You have 10 jars .Each jar has 100 marbles
9 of the 10 jars -> each marble weighs 1 gram each
last jar -> each marble weights 1.1 grams each
electronic weight scale
- place what you want to weight on it
- hit a button
- get the total weight
find the defective jar ?
Answer:Take 1 marble from jar 1, 2 from jar 2, 3 from jar 3 and so on...so u have 55 marbles in all
Weigh them all together...if total weight is 55.1....then jar 1 is the one with obese marbles...if 55.2..then jar 2...and so on... again 55.3 can't be the combination of jar 1 and 2 as (.1 +.2 ) since defective jar is only one.
