Select the number that will come in the place of the question mark(?), if ‘+’ and ‘ – ‘ are interchanged and ‘×’ and ‘÷’ are interchanged 93 – 7 ÷ 65 × 13 + 34 = ?
94
To solve this problem, we need to interchange the given mathematical operations as per the instructions:
- Interchange '+' and '–'
- Interchange '×' and '÷'
The given expression is:
\(93 - 7 \div 65 \times 13 + 34\)
After applying the interchange of operations, the expression becomes:
\(93 + 7 \times 65 \div 13 - 34\)
Now, follow the order of operations (BODMAS/BIDMAS):
- First, perform multiplication and division from left to right:
- Calculate \(7 \times 65\):
- Next, divide the result by 13:
Now, substitute back the calculated values into the expression:
\(93 + 35 - 34\)
- Perform addition and subtraction from left to right:
- Calculate \(93 + 35\):
- Then subtract 34:
The number that will come in place of the question mark is 94.
Therefore, the correct answer is option 94.
