Answer 1

Let me disclose to you a basic mathematical model. Assuming that you have 100 rupees with you and you spend the money and also note down the balance available after you spend a certain amount of money as given in the tabulation and the sum of the balances are not equal to the amount that was present initially and its greater than the actual amount by one. Similarly look at the calculation below, assume taking the same initial amount as 100 rs.

Spent- Balance

20-80

50-30

20-10

6-4

4-0

Total spent (20+50+20+6+4)=100; Total balance(80+30+10+4+0)= 124

It is always balance + spent =100, but not always the sum of the balance= 100. and so always the money spent or the expenditure must only be added instead of adding the balance.
