If * means addition, % means subtraction, @ means multiplication, and # means division, evaluate 18 @ 2 % 5 * 4 # 2.
Show answer & explanation
Correct answer: A
Explanation
Given representation of symbols:
• * means +
• % means −
• @ means ×
• # means ÷
Given expression:
18 @ 2 % 5 * 4 # 2
Replacing the symbols with mathematical operators:
= 18 × 2 − 5 + 4 ÷ 2
Applying the BODMAS rule:
= 18 × 2 − 5 + 2
= 36 − 5 + 2
= 38 − 5
= 33
Therefore, the correct option is (A).
