Question
βPβ had four Rs. 500 notes and a certain number of
Rs. 50 notes with him while βQβ had eleven Rs. 200 notes and one Rs. 500 note with him. Later βPβ was given a Rs. 100 note and now the ratio of amounts with βPβ and βQβ was 5:6, respectively. How many Rs. 50 notes did βPβ have?Solution
Let the number of Rs. 50 notes with βPβ = βyβ Then, Final amount with βPβ = (4 Γ 500 + 50y + 100) = Rs.(2100 + 50y) Amount with βQβ =(11 Γ 200 + 500) = Rs. 2700 So, according to the question, (2100 + 50y):(2700) = 5:6 Or, 2100 + 50y = 2700 Γ (5/6) Or, 2100 + 50y = 2250 Or, 50y = 150 Or, y = (150/50) Or, y = 3 Therefore, P has 3 Rs. 50 notes with him.
