Select your answer for: A and B have monthly incomes in a 5:2 ratio. B earns 12% more than C, who makes Rs. 15000 monthly. What is A's annual income?
Show answer

Answer: D. Rs. 504000

Explanation

C earns fifteen thousand monthly and B earns twelve percent more resulting in sixteen thousand eight hundred. A and B monthly incomes share a five to two ratio making A monthly income equal to forty two thousand. Multiplying A monthly income by twelve months yields an annual total of five hundred four thousand rupees. Income ratios establish proportional relationships between earnings of multiple individuals. Percentage increases are calculated by adding the percentage markup to the base reference value. Annual income is determined by multiplying the calculated monthly earnings by twelve months.

Financial planning professionals analyze salary ratios and annual earnings for tax and budgeting purposes. Corporate compensation structures often benchmark employee salaries against departmental averages. Understanding proportional income distribution helps in evaluating economic demographic data. Option A suggests four hundred twenty thousand rupees which represents a calculation error in annual scaling. Option B suggests one hundred eighty thousand rupees which mistakes monthly income for annual earnings. Option C suggests two hundred one thousand six hundred rupees which miscalculates the ratio proportion.
