They only have one flashlight and only two can cross at a time (the bridge is weak). It takes Ann 1 minute to cross, Bob 2 minutes, Charles 5 minutes and Donna 10 minutes. How can they all get across in 17 minutes?

Ann and Bob go first - 2 minutes
Ann returns - 3 minutes are up
Donna and Charles go across - 13 minutes are up
Bob returns - 15 minutes
Ann and Bob go again - 17 minutes!

Why would they need to cross in 10 minutes if they all got across in 17 ?
If they want to they could push Donna over the side for being so slow.

take Donna and Ann cross first (means 10 mins) cos Ann will take less mins than Donna, so its it will add up 10 mins..
Then take Bob with Charles,, Charles takes 5 mins, Bob just 2 minst, total of 5 mins....
those 2 groups cost 15 mins in total.... thats less than 17 mins, can give Ann alone to go back and return with Donna biggy undies...

Maybe they swam across, next to the bridge.
