  • Question
  • Which sequence of mathematical symbols can replace *in the given equation to balance the equation?
    7 * 7 * 2 * 1 = 12


  • Options
  • A. x - ÷
  • B. + - x
  • C. x - +
  • D. + x -

  • Correct Answer
  • + - x 

    Explanation

    Given, 7 * 7 * 2 * 1 = 12
    Let us check all the options one by one.
    From option (a), putting the signs in given equation, we get
    7 x 7 - 2 ÷ 1 = 12 ? 7 x 7 - 2 = 12
    ? 49 - 2 = 12 ? 47 = 12
    ? LHS ? RHS
    So, option (a) is incorrect.
    From option (b), putting the signs in given equation, we get
    7 + 7 - 2 x 1 = 12 ? 7 + 7 - 2 = 12
    ? 14 - 2 = 12 ? 12 = 12
    Hence, option (b) is correct and there is no need to check remaining options .
