    Question

    What will come in the place of the question mark (?) in the following equation, if ‘+’ and ‘−’ are interchanged and ‘×’ and ‘÷’ are interchanged?
    43 ÷ 13 − 648 × 8 + 52 = ?​

    A.

    588

    B.

    581

    C.

    586

    D.

    583

    Correct option is A

    Expression:
    43 ÷ 13 − 648 × 8 + 52 = ?
    Symbol interchanges:
    ‘+’ ↔ ‘−’
    ‘×’ ↔ ‘÷’
    Logic:
    After replacement:

    New expression becomes:
    43 × 13 + 648 ÷ 8 − 52

    Step 1: 43 × 13 = 559
    Step 2: 648 ÷ 8 = 81
    Step 3: 559 + 81 = 640
    Step 4: 640 − 52 = 588

    Final Answer: 588
    Final Correct Option: (A)
