Mintu
cat
and
Mottu
cat
were
friends.
Once
they
stole
a
chapati
from Malini’s kitchen. I will take it — said Mintu. No, I will take it
— said Mottu. While they were quarrelling, there came Tittu
Monkey. Hi! What is the problem? why are you quarrelling? — he
asked. “We don’t know how to divide this chapati between us —
the cats said. OK! don’t worry. I will divide the chapati equally for
both of you — he said. Clever Tittu divided the chapati like this:
These are not equal, the left part is bigger — Mintu and Mottu
said. Oh, no problem, I will make it equal — Tittu said. He then
cut a part of the left piece and ate it.
Oh! Now the right part is bigger — the cats cried. I am sorry —
said Tittu. He cut a part from the bigger piece and ate it. When
there was only a small piece remaining, he said — This is my
share
for
the
work.
Tittu
then
quickly
ate
the
last
piece
and
climbed the tree.
