    Solution

    ATQ,

    Let the cost price of 1,000 gm sugar be Rs. 1,000

    Cost price of 'X' gm sugar = (1,000/1,000) × X = Rs. X

    And, selling price of 'X' gm sugar = Rs. 1,000

    So, profit earned = Rs. (1,000 - X)

    Therefore, [(1,000 - X) ÷ X] × 100 = (300/17)

    Or, 17 × (1,000 - X) = 3X

    Or, 17,000 - 17X = 3X

    Or, 20X = 17,000

    So, X = (17,000 / 20) = 850

    Therefore, required value = 0.25 × 850 = 212.5
