    Question

    A person sold 20 dining tables for Rs. 5,39,000; thereby gaining the cost price of five dining tables. Find the cost price of each dining table.

    A.

    Rs. 26,950

    B.

    Rs. 25,000

    C.

    Rs. 21,560

    D.

    Rs. 27,855

    Correct option is C

    Given:

    Total selling price of 20 dining tables = Rs. 5,39,000

    Gain = Cost price of 5 dining tables

    Formula Used:

    Selling price = Cost price + Gain

    Gain = Number of items × Gain per item

    Solution:

    Let the cost price of each dining table be x

    Total cost price of 20 tables = 20x

    Gain on 20 tables = 5x

    Selling price of 20 tables = Cost price of 20 tables + Gain

    Thus,

    5,39,000 = 20x + 5x

    5,39,000 = 25x

    x = 5,39,00025\frac{5,39,000}{25}​ = 21,560

    Thus, the cost price of each dining table is Rs. 21,560
