If ‘A’ means ‘+’, ‘B’ means ‘−’, ‘C’ means ‘×’, and ‘D’ means ‘÷’, then find the value of: \((40\ D\ 5\ A\ 6\ C\ 2)\ B\ (18\ D\ 3\ C\ 2)\)?

1. 10
2. 12
3. 9
4. 8

Correct answer: 8

Solution

After substitution, the expression becomes \((40 ÷ 5 + 6 × 2) - (18 ÷ 3 × 2)\). Using BODMAS, the first bracket is 8 + 12 = 20 and the second bracket is 6 × 2 = 12. Therefore, 20 − 12 = 8.
