Question
The ratio of the pocket money of two persons βRβ and
βSβ is 6:5, respectively. βRβ spends 60% of his pocket money while βSβ spends 70% of his pocket money. If the savings of βRβ is Rs. 90 more than that of βSβ, then find the total pocket money of βRβ.Solution
Let the pocket money of βRβ and βSβ be Rs. 6x and Rs. 5x respectively
(0.4 Γ 6x) β (0.3 Γ 5x) = 90
2.4x β 1.5x = 90 β 0.9x = 90 β x = 100
Therefore, pocket money of βRβ = 6x = Rs. 600
