There are 12 products, one of which is unqualified. Give you a weightless balance. Can you find out which unqualified product is only three times and judge whether it is lighter or heavier than the genuine product?
The medicine contains 10 box, each box contains 10 box, and each box contains 100 capsules. The genuine product is per capsule 1 g, of which 1 box of defective products is only 0.9 g per capsule. There is a very sensitive weighing machine. How can we find out which box the defective product is when we can only weigh 1 time?
