    Answer: (1) 3700

    Explanation:-
    Let the original number be X

    According to the question,
    108 X/100 – 97 X/100 = 407
    (108 X – 97 X)/100 = 407
    11 X/100 = 407
    11 X = 407 x 100
    X = 407 x 100/11
    X = 37 x 100
    X = 3700

    Then, the original number is 3700.

    Hence, the answer is (1) 3700.
