Question
βPβ, βQβ and βRβ divide a certain sum of
money among themselves. The average of the amount with them is Rs. 3800. Share of βPβ is 20% more than share of βQβ and 25% less than share of βRβ. What is the share of βQβ (in Rs.)?Solution
Let share of βQβ = Rs. 100x Share of βPβ = 100x + {20% of 100x} = Rs. 120x Share of βRβ = (4/3) Γ 120x = Rs. 160x Total amount with βPβ, βQβ and βRβ, together = 3800 Γ 3 = Rs. 11400 So, 120x + 100x + 160x = 11400 Or, 380x = 11400 Or, x = 30 So, share of βQβ = 100x = 100 Γ 30 = Rs. 3000
