If '+' means 'minus', '×' means 'divided by', '÷' means 'plus' and '−' means 'multiplied by', then evaluate:
104×13+9−5÷6=?
- A-31
- B-36
- C-37
- D-34
Solution & Step-by-step Explanation
Let's replace the operators according to the given instructions:
×→÷
+→−
−→×
÷→+
Substituting these into the original expression:
104÷13−9×5+6
Now, apply the BODMAS rule (Division, Multiplication, Addition, Subtraction):
Division:
104÷13=8
The expression becomes: 8−9×5+6
Multiplication:
9×5=45
The expression becomes: 8−45+6
Addition & Subtraction:
8+6−45=14−45=−31
Therefore, the correct option is −31.
