A 79 kgs man was having a problem crossing the bridge as he read the sign board content on the bridge. "This bridge capacity is up to 80 kgs only, if you exceed this limit the bridge will fall".
He has two pieces of water melon weighing 1 kg each and he need to bring home the fruit as he promised with his kids.
Can you suggest an idea how the man can cross the bridge?

I do not believe this would work. If the absolute capacity of the bridge is 80 kg, the man weighs exactly 79 kg and each piece of watermelon weighs exactly 1 kg, the bridge would collapse from the force of the man throwing and catching the watermelon. It is actually very unlikely that the man could cross the bridge at all, even with just one piece of watermelon, as the force of each step would exceed the 80 kg limit. If the limit takes this extra force into consideration, then the man should be able to cross with both pieces by stepping very gently, and thus generating less down force.

yes you're right. but it doesn't matter on the question. i didn't emphasize this to take into consideration. this was based on a simple math.

Interesting take on the answer, but riddles should only have one possible answer. There are many different ways I could think of getting across with both watermelons.

One way of accomplishing this is stating in the riddle things like the man can not use any other objects not mentioned in the riddle, and that he can only cross the bridge once without it falling.

I agree with irninjabob about the part where the riddle should specify what objects can be used. Our man could use a helicopter to fly home. Or he could get a really really really really really really really really really really really really really really really really bouncy trampoline. Or, take the long way and find another bridge. Or use his cell phone to call up his old pal Joe who is 78Kg to carry them across for him, and when Joe is finished crossing he goes himself.
