3. I opened my mail box this morning. What do I see in it? A chain
letter. This seems to turn up every now and then in one form or
another. I began to wonder. If one person sends a certain letter to two
friends, asking each of them to copy the letter and send it to two of
their friends, those in turn each send two letters to two of their
friends and so on how many letters would have been sent by the time the
letter did thirty sets.



I calculated and I had a surprise waiting for
me. The answer was gigantic. What do you think the answer was?



4.We have a 100 m piece of ribbon.If it takes one second to cut it into

5.When I was a little girl, one day my mother had left a bowl of
goosebernes to be shared between my two sisters Lalitha, Vasantha and
myself. I went home first. I ate what I thought was my share of
gooseberries and left Then Lalitha arrived. She thought she was the
first one to arrive and ate the number of gooseberries, she thought was
her share and left. Lastly Vasantha arrived. She again thought she was
the first one to arrive and she took what she thought was her share and
left 8 gooseberries in the bowl. When we three sisters met in the
evening we realized what had happened and my mother distributed the
remaining 8 gooseberries in a fair share. How did my mother do it?
