ATQ Let the amount of money with Ravi be Rs. '100a' So, the price of 1 USB drive = (100/50) = Rs. '2a' Also, the price of 1 headphone = (100/25) = Rs. '4a' ATQ; Amount retained for the concert ticket = 0.20 X 100a = Rs. '20a' Price of 10 headphones = 10 X 4a = Rs. '40a' Remaining amount = 100a - 20a - 40a = Rs. '40a' So, number of USB drives he can purchase now = (40a/2a) = 20 Therefore, required percent = (20/50) X 100 = 40%
