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?

Solution: $11.

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).

Last Month’s Riddle: A Heavy Pill

Morris has eight unmarked bottles, each of them containing 48 identical looking pills. Five of these bottles contain only Tylenol, the rest of them contain sugar pills. Sugar pills weigh 1 milligram less than the 325 milligram Tylenol pills. Morris does not know which bottles have sugar pills and which bottles have Tylenol. Using a highly accurate digital scale only once, and the fewest pills, how can Morris identify the bottles containing the sugar pills?

Solution: Label each bottle one through eight. Take out no pills from the first bottle, 1 from the second, 2, 4, 7, 13, 24, and 44 from the third through eighth bottles respectively and weigh all 95 pills. Based on the number of milligrams short of 30,875 in the total (which could range between 3 and 81), we can calculate which bottles contain sugar pills.
