If + means ×, ÷ means -, - means ÷ then, and × means + then, what is 150 × 25 - 5 ÷ 10 + 2 = ?
Show answer & explanation
Correct answer: C
Explanation
After substitution according to the question:
150 + 25 ÷ 5 – 10 × 2
Solve according to the ‘BODMAS rule’,
150 + 25 ÷ 5 – 10 × 2
= 150 + 5 - 20
= 155 - 20
= 135
Hence, the correct answer is option 3.
