What should come in place of the question mark (?) in the following question?
2−[6−{3+(−4+5+1)×8}+12]=?
- A4
- B2
- C3
- D1
Solution & Step-by-step Explanation
Follow the BODMAS priority rules:
Inner parentheses:
−4+5+1=2
Inside curly braces:
{3+2×8}=3+16=19
Substitute back into the main expression inside square brackets:
[6−19+12]=[18−19]=−1
Final operation:
2−[−1]=2+1=3
