Education: Learn addition from the lady
Ramen-babu borrowed Rs. 250/- from his wife during the last few days of the month. The lady gave the amount to her husband without much ado. Next month, Ramen-babu again sought Rs. 250/- from his wife during the last week of the month. This time also, his wife paid the amount but said to Ramen-babu that he would have to return the amount the next month. Ramen-babu agreed.Next month, Ramen-babu asked his wife: " Dear, how much do I have to return?". She calculated and said: "Can't you calculate? You have to return Rs. 4100/-". Ramen-babu almost fainted in shock, but somehow he controlled himself and asked: "How?"
His wife showed the calculation-sheet:
250
+
250
-------
4100
She further explained her calculation very lucidly to her husband: " 2+2=4, 5+5=10, 0+0=0; Total-4100"
Poor Ramen-babu absorbed the shock and paid his wife a note of Rs. 100/-. Then he told her: "I have paid you Rs. 100/-. So, now I am required to pay Rs. 4/-, isn't it?". His wife agreed. Ramen-babu took out his purse and gave his wife two coins of Rs. 2/-. His wife was satisfied. She said: "Okay, you have paid the full amount."
In the evening, Ramen-babu took his wife to the market and both enjoyed consuming golgoppa/panipuri.
