If ‘+’ means ‘-’, ‘-’ means ‘×’, ‘×’ means ‘÷’ and ‘÷’ means ‘+’, then solve the following expression:
43−2×2+8=?
- A42
- B35
- C25
- D40
Solution & Step-by-step Explanation
First, let's substitute the operators according to the given conditions:
− becomes ×
× becomes ÷
+ becomes −
Substituting these into the given expression:
Original Expression: 43−2×2+8
New Expression: 43×2÷2−8
Now, apply the BODMAS rule to solve it:
Division first:
2÷2=1
So, the expression becomes: 43×1−8
Multiplication:
43×1=43
Subtraction:
43−8=35
− becomes ×
× becomes ÷
+ becomes −
Substituting these into the given expression:
Original Expression: 43−2×2+8
New Expression: 43×2÷2−8
Now, apply the BODMAS rule to solve it:
Division first:
2÷2=1
So, the expression becomes: 43×1−8
Multiplication:
43×1=43
Subtraction:
43−8=35
