Chapter 9

House of Hundreds - II 

One day, Akbar and Birbal were walking in a garden. Many crows were flying in the sky around them. Akbar was curious to know how many crows there were.

He announced a prize for anyone who could find this out. People were wondering how to count crows which kept flying from one place to another. Akbar asked Birbal if he could figure this out.

After thinking for a day, Birbal said “There are exactly Nine Hundred and Sixty Three crows in our city”.

Akbar was surprised and asked Birbal, “How can you be so sure”?
“You can get them counted,” said Birbal.
“What if there are less?” asked Akbar.
“The other crows would have gone on a holiday,” said Birbal.
“What if there are more?” asked Akbar.
“Crows from other places would be visiting the city,” said Birbal.
Akbar was happy with Birbal’s reply and gave him the reward.
