Answer» Correct Answer - Option 2 : 750, 900 Given: The income of P and Q ratio = 5 : 6 And expenditure ratio = 5 : 8 Each saves = Rs. 500 Formula used: Income = Expenditure + saving Calculations: Let Income = 5x and 6x Income – saving = expenditure According to the question ⇒ (5x – 500)/(6x - 500) = 5/8 ⇒ 40x – 4000 = 30x – 2500 ⇒ 10x = 1500 ⇒ x = 150 P’s income = 5 × 150 = Rs. 750 Q’s income = 6 × 150 = Rs. 900 ∴ P and Q’s income is Rs. 750 and Rs. 900 respectively. |
