Show answer & explanation
Correct answer: D
Explanation
Given expression: 30 # 4 @ 2 % 6 * 3
According to the given conditions, replace the symbols with their respective mathematical signs:
• # represents ×
• @ represents ÷
• % represents −
• * represents +
Substituting the signs into the expression:
30 × 4 ÷ 2 − 6 + 3
Applying the BODMAS rule:
• Division: 4 ÷ 2 = 2
⇒ 30 × 2 − 6 + 3
• Multiplication: 30 × 2 = 60
⇒ 60 − 6 + 3
• Addition & Subtraction:
⇒ 60 + 3 − 6 = 63 − 6 = 57
Therefore, the correct answer is (D) 57.
