Given:
A = ÷ , B = × , C = + , D = −
Expression:
68 A 2 D 7 B 5 C (25 A 5) B 9 C 30 A 6
Step 1: Replace symbols
68 ÷ 2 − 7 × 5 + (25 ÷ 5) × 9 + 30 ÷ 6
Step 2: Solve brackets
(25 ÷ 5) = 5
So expression becomes:
68 ÷ 2 − 7 × 5 + 5 × 9 + 30 ÷ 6
Step 3: Apply BODMAS (÷, × first)
68 ÷ 2 = 34
7 × 5 = 35
5 × 9 = 45
30 ÷ 6 = 5
Now substitute:
34 − 35 + 45 + 5
Step 4: Final calculation
34 − 35 = −1
−1 + 45 = 44
44 + 5 = 49
✅ Correct Answer: 49
