Answer 1

Hi there!
Here's the answer:

Total money = 100

Spent…………………Left
40………………………60
30………………………30
18 ………………………12
12 ………………………0.

The total of amount spent is added gives the initial total amount.
It can be added directly.

But the values mentioned in spent are calculated cumulatively(taking into account previous values).

Therefore adding this'd values cannot sum up to initial total amount

¶¶ The left amount for the amount spent is calculated CUMULATIVELY, that's the only reason.

:)
Hope it helps
