Hi All
Can you guys work on this....
There are 20 packs of cigarettes. Each pack has 20 cigarettes. Each pack has cigarettes weighing 2gms each except one pack. Cigarettes in this only pack weigh 1gm each. All 20 packs are randomly mixed. You have a balance and you CAN balance ONLY ONE TIME. How will you find which pack has 1gm cigarretes?
