Correct option is D
Given:
Ratio of incomes of David and Ashish = 5 : 8
Savings of each = 81000
Ratio of their expenditures = 2 : 4
Formula Used:
Income - Savings = Expenditure
Solution:
Let the monthly incomes of David and Ashish be 5x and 8x.
Expenditure of David = 5x - 81000
Expenditure of Ashish = 8x - 81000
Ratio of their expenditures is 2 : 4, which simplifies to 1 : 2.
2(5x - 81000) = 1(8x - 81000)
10x - 162000 = 8x - 81000
2x = 81000
x = 40500
Monthly income of David = 5x = 5 × 40500 = 202500
Final Answer
So the correct answer is (d)
