If % = multiplication, @ = subtraction, $ = addition, and # = division, what is 50 % 4 $ 20 @ 15 # 5?
Show answer & explanation
Correct answer: A
Explanation
Given:
50 % 4 $ 20 @ 15 # 5
% = ×, @ = −, $ = +, # = ÷
After substitution:
50 × 4 + 20 − 15 ÷ 5
Solve according to BODMAS rule:
= 50 × 4 + 20 − 15 ÷ 5
= 200 + 20 − 3
= 220 − 3
= 217
Hence, the correct answer is option 1.
