I have 100 rupees

Question

I have 100 rupees 

Spend.                    Balance

  40                              60

  30                              30

  18                              12

  12.                              00

 

So spend amount is coming 100 but my balance comes 102 , how is it possible 

Both should be same 

Please give any suggestions

 

Answer 1

You don't add the balance numbers. They are the result after spending. 

 

Balance 0 + Spend 12 = Balance 12

 

Balance 12 + Spend 18 = Balance 30

 

Etc.
