- 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
ExplanationGiven, 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
