Detailed Solution
Download Solution PDFGiven:
The ratio of savings to expenditure of a woman is 2 ∶ 1.
Income increase = 17%
Expenditure increase = 13%
Formula Used:
Savings = Income - Expenditure
Calculations:
Let the original savings be 2x and the original expenditure be x.
Therefore, the original income = savings + expenditure = 2x + x = 3x.
New income = 3x × 1.17 = 3.51x
New expenditure = x × 1.13 = 1.13x
New savings = New income - New expenditure = 3.51x - 1.13x = 2.38x
Percentage increase in savings = (New savings - Original savings) / Original savings × 100
Percentage increase in savings = (2.38x - 2x) / 2x × 100 = 0.38x / 2x × 100 = 19%
∴ The percentage increase in her savings is 19%.
