    A Rs 175 Correct Answer Incorrect Answer
    B Rs 168 Correct Answer Incorrect Answer
    C Rs 200 Correct Answer Incorrect Answer
    D Rs 120 Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    Let the cost price of earphone be 8t
    Selling price of earphone = 8t + (3/8) x 8t = 11t
    Let the cost price of charger be 25y
    Selling price of charger = 25y - (1/25) x 25y = 24y
    Given, 11t = 275
    => t = 25
    Cost price of the earphone = 8t = 8 x 25 = Rs. 200
    Hence, cost price of charger = 375 - 200 = Rs. 175
    => 25y = 175
    => y = 7
    Hence, required selling price of the charger = 24y = 24 x 7 = Rs. 168
