What will come in place of the '?' in the following equation, if '+' and '-' are interchanged and 'x' and '÷' are interchanged? 56 +12 - 54 x 18 ÷ 6 = ?
To solve the problem, we need to interchange the given mathematical operators: replace '+' with '-', '-' with '+', 'x' with '÷', and '÷' with 'x'. Given equation: 56 + 12 - 54 x 18 ÷ 6 = ?
Applying the operator interchange:
56 - 12 + 54 ÷ 18 x 6 = ?
Now, follow the standard order of operations (BODMAS/BIDMAS), which is Brackets, Orders (i.e., powers and roots), Division and Multiplication (from left to right), Addition and Subtraction (from left to right).
First, perform the division and multiplication:
54 ÷ 18 = 3
Then result multiplied by 6:
3 x 6 = 18
Next, perform the addition and subtraction from left to right:
56 - 12 = 44
44 + 18 = 62
Therefore, the value of '?' is 62.
| Options | Value |
| 62 | Correct |
| 50 | Incorrect |
| 86 | Incorrect |
| 26 | Incorrect |
