80 Kg Only - 

Answer

Age group: All

The question was:

"John, a party magician, is carrying three bars of gold, each weighing one kilogram. On the way to a session, he comes to a bridge, which has a sign posted saying the bridge can bear a weight of only 80 kilograms. John weighs 78 kilograms and the gold weighs 3 kilograms in total. He read the sign and still safely crossed the bridge with all the gold in one go.

How did he manage to do this?"

Now coming to the Answer!

We are going to use the concept of weightlessness, i.e. during free fall, the body is weightless.

John, being a party magician, can cross the bridge in one go by juggling the three bars of gold, such that one of the bars is always in the air, under free fall, which results in the total weight being 80 Kg at all times.
