Mr. X spends 20% of his monthly income on household expenditure. Out of the remaining 25% he spends on children's education,15%on transport, 15% on medicine and 10%on entertainment. He is left with Rs. 9,800after incurring all these expenditures. What is his monthly income?
Explanation:
Let Mr X’s salary be Rs p
His household expenditure=0.2p
Salary left after household expenditure=0.8p
Spending on childrens education=0.25×0.8p=0.2p
Spending on transport=.15×0.8p=0.12p
Spending on medicine=.15×0.8p=0.12p
Spending on entertainment=0.10×0.8p=0.08p
Mr X s total expenditure=0.2p+0.2p+0.12p+0.12p+0.08p=0.72p
So 0.28p=9800
p=35,000
