    Answer:  (3) 1250 

    Explanation:-
    Let the two numbers be X and Y.

    The sum of two numbers is 75
    Then, X + Y = 75  …………………………. (1)

    The difference two numbers is 25
    Then, X  – Y = 25  ………………………… (2)

    As we know that, (X + Y)² – (X – Y)² = 4 X Y
    Now, From equation (1) & (2),
    75² – 25² = 4 X Y
    5000 – 625 = 4 X Y
    5000 = 4 X Y
    X Y = 5000/4
    X Y = 1250

    Then, the product of the numbers is 1250.

    Hence, the answer is (3) 1250.
