    What will come in the place of the question mark '(?)' in the following equation, if '÷' and '×' are interchanged and '+' and '-' are interchanged?
    20 - 7 ÷ 4 + 20 × 4 = ?

    A.

    43

    B.

    41

    C.

    44

    D.

    42

    Correct option is A

    Given: ​20 - 7 ÷ 4 + 20 × 4 = ?
    ​​
    After interchanging the sign in the given equation will be:
    ​20 + 7 × 4 - 20 ÷ 4 = ?
    ? = 20 + 7 × 4 - 5
    ? = ​​​20 + 28 - 5
    ? = 48 - 5
    ? = 43
    Thus, the correct option is (a) 43.
