A Problem of Gooseberries
When I was a little girl, one day my mother had left a bowl of gooseberries 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 arrives. 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 reliazed what had happened and my mother distributed the remaining 8 gooseberries in a fair share.
How did my mother do it?
