    A shopkeeper bought three items: a television for Rs. 10p,

    a refrigerator for Rs. 20p, and an air conditioner for Rs. 50p. The average price of these items is Rs. 60,000. What is the price difference (in Rs.) between the air conditioner and the television?
    A 94010 Correct Answer Incorrect Answer
    B 84430 Correct Answer Incorrect Answer
    C 90000 Correct Answer Incorrect Answer
    D 74160 Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    ATQ;
    Total cost = average × number of products = 60000 × 3 = 180000

    Hence, 10p + 20p + 50p = 80p = 180000 ⇒ p = 2250

    Difference = (50p − 10p) = 40p = 90,000
