Question

मेरे पास 50/- रूपए थे।

दिनांक खर्च किये बाकी बचे
12-9 20/- 30/-
13-9 15/- 15/-
14-9 09/- 06/-
15-9 06/- 00/-
---- -----
50/- 51/-

अब ये 1/- रूपया ज्यादा खर्च केसे हो गया?

अपनी अभी तक की पढाई को परखे और बुद्धिमान होने की जानकारी सब को दें।

Answer 1

There is no relation between these two numbers in the transaction...One column is money spent another is remaining money after each transaction and summing it does not make any sense. Try to spend 1 Rs at a time and then you see by the same logic you have other column have SUM(49, 48, ....9, 0).
Now I hope things would be clear
