Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 10,000
66% more = 2/3
It ,means, if the saving are Rs3 then the expenditures are (3 + 2) = 5
Let the savings = 300x
Expenditure = 500x
So income = 300x + 500x = 800x
Income increased by 44%
So monthly income = 800 × 144/100 = 1152x
Expenditure increased by 60% = 500x × 160/100 = 800x
Savings = 1152x - 800x = 352x.
Increase in the savings = 352x - 350x = 52x
52x = 1040
x = 20
Expenditures = 500 × 20 = 10000.
