Question
Neha goes to a toy store with some money. She can buy 60
dolls or 20 robots with the money with her. However, instead of spending the entire amount, she saves 5% of the amount for candies and buys 8 robots and some dolls. Find the percentage of number of dolls she can purchase now out of the initial number of dolls she could have purchased.Solution
ATQ Let the amount of money with Neha be Rs. '180c' So, the price of 1 doll = (180/60) = Rs. '3c' Also, the price of 1 robot = (180/20) = Rs. '9c' ATQ; Amount retained for candies = 0.05 X 180c = Rs. '9c' Price of 8 robots = 8 X 9c = Rs. '72c' Remaining amount = 180c - 9c - 72c = Rs. '99c' So, number of dolls she can purchase now = (99c/3c) = 33 Therefore, required percent = (33/60) X 100 = 55%
