Question
Simran goes to a grocery store with some money. She can
buy 80 packets of rice or 40 packets of flour with the money with her. However, instead of spending the entire amount, she saves 10% of the amount for a donation and buys 20 packets of flour and some packets of rice. Find the percentage of number of rice packets she can purchase now out of the initial number of rice packets she could have purchased.Solution
ATQ Let the amount of money with Simran be Rs. '320e' So, the price of 1 rice packet = (320/80) = Rs. '4e' Also, the price of 1 flour packet = (320/40) = Rs. '8e' ATQ; Amount retained for donation = 0.10 X 320e = Rs. '32e' Price of 20 flour packets = 20 X 8e = Rs. '160e' Remaining amount = 320e - 32e - 160e = Rs. '128e' So, number of rice packets she can purchase now = (128e/4e) = 32 Therefore, required percent = (32/80) X 100 = 40%
