Answer 1

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

Answer 2

Solution :-

1) Initially had money = Rs. 100

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 spent all your money. You are adding the money left with you. This is the mistake you are doing. Just add the money spent by you which is equal to Rs. 100
