Junoo, the madman, observed the proceedings with great interest. He went into a trance and said:

With a bit of mind
We sure will find
A way much better
Than to weigh them all together!

Weigh twenty persons one by one
Add their weights and when that is done
Divide by twenty and the average you will get
And then its so simple, I sure can bet.

A little lateral thinking
A little maths for all
And then there is no problem
We cannot solve!

Thus was the weighing problem resolved. Finally Lulu got a heap of coins as high as a hill.

Now Lulu was in a quandary. How was he going to carry all these coins? An advisor to the chieftain, leaned over and whispered something into the chieftain's ear. The chieftain seemed to like the idea.
