खुला चैलेंज ग्रुप जरा सोल्व करे। मेरे पास 100/- रूपए थे। *खर्च किये* *बाकी बचे* चावल- 40/- 60/- सब्जी- 30/- 30/- चाय- 18/- 12/- पकोडी- 12/- 00/- ---- ----- कुल *100/-* *102/-* अब ये *2/-* रूपया ज्यादा खर्च केसे हो गया सुबह से दिमाग ख़राब है

Answer 1

Total amount -100/-

Item ---------------Expenses incurred--------Remaining amount
Rice--------------------40/-                                 60/-

Out of remaining 60/-, following is the calculation
 
Vegetable------------30/-                                  30/-

Out of remaining 30/-, following is the calculation
Tea---------------------18/-                                  12/-

Out of remaining 12/-, following is the calculation
Snack-----------------12/-                                    00/-

So, total expenses is actually 100/- only. 102/- is just a mere calculation to divert the attention. In Mathematics, we calculate the remainder after subtracting the expenditure from the total amount. we never calculate the remainder after each expense occurring.

The actual remainder is zero at the end as total 100/- has been expensed.
