Question
Out of his total income, Rohan spent 20% on groceries,
30% on school fees and 10% on rent. If he spent 30% of the remaining on entertainment and saved the rest which is Rs. 560, then find his total income.Solution
Let total income of Rohan be Rs. '100x' So, amount left after he spent part of it on groceries, school fees and rent = 100x - (0.20 + 0.30 + 0.10) X 100x = Rs. '40x' So, 0.70 X 40x = 560 Or, x = (560/28) = 20 So, total income of Rohan = 100x = 100 X 20 = Rs. 2,000 Hence, option c.
- The price of a product is first reduced by 15% and then increased by 25%. If the final price is ₹690, then find the original cost price.
