Riddle: The Broken Scale
Submitted by: David Dweck
Mrs. Abadi, Mrs. Beyda and Mrs. Cohen come into the doctor’s office, each with their own pair of identical twin babies. The nurse wants to weigh the babies, but her regular scale is broken and she only has a balance scale with which she can compare the weight of two or more babies. Mrs. Cohen tells the nurse that she is sure that her lighter baby weighs exactly the same as one of the Abadis and one of the Beydas. Mrs. Beyda is also sure that her heavier baby weighs exactly the same as one of the Cohens and one of the Abadis. How can the nurse determine which baby in each set of twins are the lighter ones by using the balance scale only twice?
Last Month’s Riddle: Husbands and Wives
Three couples are at the bottom floor of a tall building and want to get to the top. The elevator cost $1 to ride in each direction, can only hold two people at a time, and needs at least one person inside to operate. None of the wives can be in the presence of another man, unless her husband is also present. What is the minimum it will cost for all three couples to get to the top?
One couple goes up ($1) and the husband comes back down ($2). Two wives go up ($3) and one comes back down ($4). The two wives whose husbands are at the top go up ($5) and one of the couples comes back down ($6). Two husbands go up ($7) and the wife at the top comes down ($8). Two wives go up to join their husbands ($9) and the husband whose wife remained at the bottom goes down ($10) to bring his wife up to the top ($11).

Roslyn hands a sealed envelope with $8 to Paulette. Paulette notices that when she shakes the envelopes she does not hear the rattling of coins inside. But Roslyn maintains that although the envelope contains $8 in American money, there are only two bills inside. How is this possible?
Solution: Roslyn has a $5 bill, a $2 bill and a $1 coin – which by itself would not make any rattling sound inside the envelope.
