The ratio of the pocket money of two persons βPβ and
βQβ is 5:2, respectively. βPβ spends 60% of his pocket money while βQβ spends 25% of his pocket money. If the savings of βPβ is Rs. 150 more than that of βQβ, then find the total pocket money of βPβ.Solution
Let the pocket money of βPβ and βQβ be Rs. 5x and Rs. 2x respectively
(0.4 Γ 5x) β (0.75 Γ 2x) = 150
2x β 1.5x = 150 β 0.5x = 150 β x = 300
Therefore, pocket money of βPβ = 5x = Rs. 1500
