Question
Monthly savings of βQβ is 20% more than that of
βPβ and is 54% less than monthly income of βPβ. Monthly expenditure of βQβ is Rs. 5730 and ratio of monthly income of βPβ and βQβ is 15:26, respectively. Find monthly expenditure of βPβ.Solution
Let monthly income of βPβ and βQβ be Rs. β15xβ and Rs. β26xβ, respectively Monthly savings of βQβ = 46% Γ 15x = Rs. 6.9x Monthly savings of βPβ = {6.9/1.2} = Rs. 5.75x Monthly expenditure of βPβ = 15x β 5.75x = Rs. 9.25x Monthly expenditure of βQβ = 26x β 6.9x = Rs. 19.1x Or, 19.1x = 5730 Or, x = 5730/19.1 Or, x = 300 Monthly expenditure of βPβ = 9.25 Γ 300 = Rs. 2775
