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.
