• C. Rs. 135,000
• D. Rs. 119,000

Answer 1

Answer:

C. Rs. 135,000

Let Income of Radha and Rani be 3x and 2x and Expenditure be 8y and 5y Saving = 3x – 8y = 2x – 5y ⇒ x = 3y ⇒ 3x – 8y = 9,000 ⇒ 3(3y) – 8y = 9,000 ⇒ 9y – 8y = 9,000 ⇒ y = 9,000 x=27000 Total income of Radha and Rani = 5x = 5 ×27000 = 1,35,000
