The ratio of expenditure to saving of a person is 26 : 3. If the monthly income is ₹ 7250, what is the monthly saving?
Correct Answer: ₹ 750
Introduction / Context:Income equals expenditure plus saving. Given the ratio expenditure : saving, we can treat income as the sum of parts, then compute the value of one part from the total income to get the saving.
Given Data / Assumptions:
- Expenditure : Saving = 26 : 3
- Income = ₹ 7250
- Income = (26 + 3) parts = 29 parts
Concept / Approach:Find one-part value by dividing income by 29. Multiply the one-part value by 3 to get savings. This is a direct part-to-total conversion.
Step-by-Step Solution:Total parts = 26 + 3 = 29One part = 7250 / 29 = 250Saving = 3 parts = 3 * 250 = ₹ 750
Verification / Alternative check:Expenditure = 26 parts = 26 * 250 = ₹ 6500. Income check: 6500 + 750 = 7250.
Why Other Options Are Wrong:290, 350, 780, 680 are not 3 out of 29 parts of 7250; they break the ratio when recomputed.
Common Pitfalls:Interchanging the order to “saving : expenditure”; always align parts with the given order.
Final Answer:₹ 750
