  • Question
  • 7   4   8   2 = 24


  • Options
  • A. -, x and x
  • B. -, x and ÷
  • C. x, - and ÷
  • D. x, ÷ and -

  • Correct Answer
  • x, - and ÷ 

    Explanation

    Let us check all the options one-by-one.
    From option (a),
    7 - 4 x 8 x 2 = 24 (using VBODMAS rule)
    ? 7 - 64 = 24 ? -57 = 24
    ? LHS ? RHS ? RHS
    So, option (a) is incorrect.

    From option (b),
    7 - 4 x 8 ÷ 2 = 24 (using VBODMAS rule)
    ? 7 - 4 x 8 ÷ 2 = 24 (using VBODMAS rule)
    ? 7 - 4 x 4 = 24 ? 7 - 16 = 24
    ? -9 = 24 ? LHS ? RHS
    So, option (b) is incorrect .
    From option (c),
    7 x 4 - 8 ÷ 2 = 24 (using VBODMAS rule)
    ? 7 x 4 - 4 = 24 ? 28 - 4 = 24
    ? 24 = 24 ? LHS = RHS
    So, option (c) is correct and hence, there is no need to check option (d).
