Question
Monthly savings of βQβ is 25% more than that of
βPβ and is 56% less than monthly income of βPβ. Monthly expenditure of βQβ is Rs. 4100 and ratio of monthly income of βPβ and βQβ is 15:23, respectively. Find monthly expenditure of βPβ. MTSolution
Let monthly income of βPβ and βQβ be Rs. β15xβ and Rs. β23xβ, respectively Monthly savings of βQβ = 44% Γ 15x = Rs. 6.6x Monthly savings of βPβ = {6.6/1.25} = Rs. 5.28x Monthly expenditure of βPβ = 15x β 5.28x = Rs. 9.72x Monthly expenditure of βQβ = 23x β 6.6x = Rs. 16.4x Or, 16.4x = 4100 Or, x = 4100/16.4 Or, x = 400 Monthly expenditure of βPβ = 9.72 Γ 250 = Rs. 2430
