Four members of a band are walking to a night concert. They decide to take a shortcut, but must cross a bridge. Luckily they have one flashlight. Because of the varying size of their instruments, it takes each member a different amount of time to cross the bridge - it takes the first person one minute, the second person two minutes, the third person five minutes and the fourth person ten minutes. They must cross the bridge in pairs, traveling at the slower speed so if the one minute person went with the ten minute person, it would take a total of ten minutes. Since there is only one flashlight, one person must come back across the bridge, then another pair can cross. They only have 17 minutes to cross the bridge and still get to the concert on time. What order should they cross to get everyone across and get to the concert?

Answer

First, the one minute person and the two minute person must cross the bridge, for a total of two minutes. Then the one minute person should come back with flashlight - total of three minutes. The five minute person and the ten minute person cross together next, making the total thirteen minutes. Now the two minute person goes back and (total now fifteen minutes) and gets the one minute person and they cross together bringing the total to seventeen minutes.

A woman with three very sick children has a 24oz. botttle of medicine and each child needs 8 oz. of medicine. She has a 5 oz. cup, a 11 oz. cup, and a 13 oz cup. Each cup can only go to one child and cannot be used more than once. With these 4 items, can she measure 8 oz. for each child? How?

Empty both the 5 and 11 oz. cups back into the bottle.
Transfer the medicine in the 13 oz. cup into the 11 oz. cup.
Pour 13 out of the 16 oz. in the bottle into the 13 oz. cup.
Pour 5 oz. of the 13 oz. cup into the 5 oz. cup.
Pour the 5 oz. in the 5 oz. cup back into the 24 oz. bottle.
You should now have 8 oz. in the 24 oz. bottle, the 11 oz. cup, and the 13 oz. cup. *The 5 oz.. cup is empty.
