Lets say there were 4 men who went to a town to buy things for their fishing trip. 2 of them bought oars and two bought roap. on the way home they came across a river. the only way they could cross it is by rowing in a boat. only 2 can go across each time. how can yo0u get all four of them over to the other side

I'm a little confused as to how all the men went to town just fine, but on the way back home somehow encountered a river.

Wait! maybe there is another condition that he forgot to state, but meant to. Maybe the people can only use what they bought, two can only use oars, and the other two an only use rope... This would make it at least a little more interesting...

And lol Lausus I didn't even think of that!

Well, it is very possible to row a small boat with only one oar, so you wouldn't need two oarmen.

But I doubt he would be able to row very well with someone else in the boat. Maybe if he was by himself, but it would be too crowded with company (at least in the type of boat I'm thinking of)

I wonder... In the original question it states "Two of them bought oars" does this mean two of them bought one oar each? or two of them bought two oars each? More importantly, does it make a difference?

Hmmm, it just became more difficult. We are not told the men actually had a boat, only that one was necessary. They now need to use the (assumed) two oars and rope to build a boat.

And since it never states how many oars or how much rope were purchased, they obviously bought plenty of oars, and rope, and made a boat like you mentioned. Then use the leftover oars to row across in the 2, 1 back, 2, 1 back fashion.
