A person saves 40% of his income. If his expenditure is ₹960, then his income (in ₹) is:
Given:
Saving = 40% of income
Expenditure = ₹960
Solution:
Expenditure = (100% − Saving%) × Income = 60% of Income
Income = Expenditure ÷ 0.60
Income = ₹960 ÷ 0.60 = ₹1600
Alternate Method:
Saving : Expenditure = 40 : 60 = 2 : 3
If 3 parts = 960
1 part = 320
Total income = (2 + 3) parts = 5 parts = 5 × 320 = ₹1600
