A man walks past a beggar every day and gives him Rs. 10 and that Continues for a year.
Then suddenly the daily donation changes to Rs. 7. 50. ”Well,” the beggar thinks, ” it’s still better than nothing.”
A year passes in this way until the man’s daily donation suddenly becomes Rs. 5.
”What’s going on now?” the beggar asks his donor. ” First you give me Rs. 10 every day, then Rs. 7.50 and now only Rs. 5. What’s the problem?”
”Well,” the man says, “ last year my eldest son went to university, it’s very expensive, so I had to cut costs”.”This year my eldest daughter also went to university, so I had to cut my expenses even further”
”And how many children do you have?” the beggar asks.
” Four,” the man replies.
