    Question

    Select correct combination of mathematical signs to sequentially replace the (@) signs and balance the following equation.
    28@7@12@6@8

    A.

    ÷,×,=,-

    B.

    ×,=,-÷

    C.

    ÷,×,=,×

    D.

    ×,÷,=,-

    Correct option is C

    Given:
    28 @ 7 @ 12 @ 6 @ 8
    Logic:
    The task is to insert appropriate mathematical signs to make the equation valid. We check the combination by applying each option step by step to see if it balances the equation.
    Let's check each option:

    Option (a): ÷ ,  × ,  = ,  -

    28 ÷ 7 ×12 = 6 - 8

    4 × 12 = ( -2 )
    48 = (-2) (false)

    Option (b): ×, =, -, ÷

      28 × 7 = 12 - 6 ÷ 8
      196 = 11.25 (false)

      Option (c): ÷, ×, =, ×

        28 ÷ 7 × 12 = 6× 8
        4 × 12 = 48
        48 = 48 (true)

        Option (d): ×, ÷, =, -

          28 × 7 ÷ 12 = 6 - 8
          196 ÷ 12 = - 2
          16.33 =  - 2  (false )
          the correct answer is option ( c )​
