Answer» Correct Answer - Option 2 : Rs. 12,000 Given: The income of Ravi is 50% more than Lalit’s income Their expenditures are in the ratio 5 : 3. Calculation: Income of Ravi = (100 + 50)/100 of Lalit’s income ⇒ Ravi/Lalit = 3/2 Let income of Ravi and Lalit be 3x and 2x respectively Also, their expenditure is 5y and 3y Now, according to equation, ⇒ 3x – 5y = 2000 ----(1) ⇒ 2x – 3y = 2000 ----(2) Now, Multiplying equation (1) by 3 and equation (2) by 5. ⇒ 9x – 15y = 6000 ----(3) ⇒ 10x – 15y = 10000 ----(4) Now, subtract from equation (4) from equation (3) ⇒ x = 4000 Then, income of Ravi = 3x = 3 × 4000 ⇒ Rs. 12,000 ∴ Ravi’s income is Rs. 12,000 rupees. |
