Answer:
2142
Step-by-step explanation:
10%+20%+15%=45% which means Amit gave away total 45%of his money. Therefore remaining is 55%. Since he has 1224rs remaining it means 55% = 1224 rs. If 55% is 1224, then divide on both sides by 24 you will get 2.5%=51. Now multiply on both sides with 18 you will get 2.5%×18= 51×18 that is, 45%= 918. Now add 918 + 1224 you will get original sum of money = 2142
