The ratio of the monthly incomes of A and B is 11 : 13 and the ratio of their expenditures is 9 : 11. If both of them manage to save Rs 4,000 per month, then find the difference in their incomes (in Rs).
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 4,000
The ratio of the income of A : B = 11 : 13
The ratio of the expenditure A : B = 9 : 11
Income - Expenditure = Savings
So, saving of each person (11 - 9) = 4000 = (13 - 11)
2 = 4000
1 = 2000
So, the difference in their incomes = (13 - 11) × 2000 = Rs 4000
