You have three sealed boxes labeled 1, 2, and 3. One of these boxes contains $10, the other $15, and the last $20 in five dollar bills. Unfortunately, they have been labeled wrong. Box 1 is labeled $10, Box 2 is labeled $15, and Box 3 is labeled $20. Someone opens Box 2, and finds 2 five dollar bills ($10). Based on this information, can you tell what amounts are in Box 1 and Box 3 without opening them?
Vova  I tried drawing it and I must be doing something wrong. Can you explain how you drew it to me? Thank you.
