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%
