    A Rs.2050 Correct Answer Incorrect Answer
    B Rs.2700 Correct Answer Incorrect Answer
    C Rs.1900 Correct Answer Incorrect Answer
    D Rs.2250 Correct Answer Incorrect Answer

    Solution

    ATQ,

    Let the new commission of the salesperson be Rs. '100x'

    So, old commission of the salesperson = 100x × 0.82 = Rs. '82x'

    So, 100x - 82x = 450

    So, 18x = 450

    So, x = 25

    So, old commission of the salesperson = 25 × 82 = Rs. 2,050
