    Let the business value change from A to B.
    Then, 4% of A = 5% of B
    ⇒ 4A/100 = 5B/100
    ⇒ B = 4A/5
    ∴ change in business = (A - 4A/5) = A/5

    Correct Option: C

    Let the business value change from A to B.
    Then, 4% of A = 5% of B

    ⇒ B = 4A/5
    ∴ change in business = (A - 4A/5) = A/5
    Percentage slump in business = {(A/5)/A} x 100 % = 20%
