Question
Monthly savings of βQβ is 20% more than that of βPβ and is 48% less than monthly income of βPβ. Monthly expenditure of βQβ is Rs. 4260 and ratio of monthly income of βPβ and βQβ is 15:22, respectively. Find monthly expenditure of βPβ.
Solution
Let monthly income of βPβ and βQβ be Rs. β15xβ and Rs. β22xβ, respectively Monthly savings of βQβ = 52% Γ 15x = Rs. 7.8x Monthly savings of βPβ = {7.8/1.2} = Rs. 6.5x Monthly expenditure of βPβ = 15x β 6.5x = Rs. 8.5x Monthly expenditure of βQβ = 22x β 7.8x = Rs. 14.2x Or, 14.2x = 4260 Or, x = 4260/14.2 Or, x = 300 Monthly expenditure of βPβ = 8.5 Γ 300 = Rs. 2550Β Β
