Answer 1

Solution :-

Initially had money = Rs. 100

1) Money spent = Rs. 40
    Money left = Rs. 100 - Rs. 40 = Rs. 60

2) Money spent = Rs. 30
    Money left = Rs. 60 - Rs. 30 = Rs. 30

3) Money spent = Rs. 18
    Money left = Rs. 30 - Rs. 18 = Rs. 12

4) Money spent = Rs. 12
    Money left = Rs. 12 - Rs. 12 = 0

So, you have left with no money. Always remember that you cannot spend more money than you actually have. You had Rs. 100 with you initially and you spent that money. You cannot spend more than Rs. 100.

You are adding the money left with you. This is the mistake, you are doing. Just add the money spent by you. 

 

Answer 2

हिसाब लगाने का सही तरीका इस प्रकार है :

आपके पास Rs.100 - 40 खर्च किये = 60  बचे

आपके पास Rs.60 - 30 खर्च किये = 30 बचे

आपके पास Rs.30 - 18 खर्च किये = 12 बचे  

आपके पास Rs.12 - 12 खर्च किये = 0 कुछ पैसे नहीं बचे
