Question
Neha goes to a bookstore with a certain amount of money.
She can buy 60 notebooks or 20 novels with the money she has. However, she saves 15% of the amount for a trip and buys 5 novels and some notebooks. Determine the percentage of notebooks she can now purchase out of the initial number of notebooks she could have bought.Solution
ATQ Let the amount of money with Neha be Rs. '80a' So, the price of 1 notebook = (80/60) = Rs. '1.33a' Also, the price of 1 novel = (80/20) = Rs. '4a' ATQ; Amount retained for the trip = 0.15 X 80a = Rs. '12a' Price of 5 novels = 5 X 4a = Rs. '20a' Remaining amount = 80a - 12a - 20a = Rs. '48a' So, number of notebooks she can purchase now = (48a/1.33a) ≈ 36 Therefore, required percent = (36/60) X 100 = 60%
