Question

What will be the correct mathematical signs that can be inserted in the following? \[ 8 \ \_ \ 6 \ \_ \ 2 \ \_ \ 4 \ \_ \ 8 \;=\; 28 \]

• A. \( - \ \times \ + \ \div \)
• B. \( \div \ + \ \times \ - \)
• C. \( + \ \div \ - \ \times \)
• D. \( \times \ \div \ - \ + \)

Hint:

Always apply operator precedence: first \(\times,\div\) left to right, then \(+,-\). Testing choices quickly often reveals the match.

Answer 1

The Correct Option is D

Step 1: Substitute option (d) and apply BODMAS.
\[ 8 \times 6 \div 2 - 4 + 8 \] First multiplication: \(8\times 6=48\). Then division: \(48\div 2=24\).
Now addition/subtraction left to right: \(24-4+8=20+8=\boxed{28}\).
