3. 15 + 5 − 2 ÷ 6 × 3 = 3
4. 15 − 5 + 2 × 6 ÷ 3 = 41
Options
- A3
- B1
- C2
- D4
Correct answer
A. 3
Step-by-step solution
From the third equation, we get
15 + 5 − 2 ÷ 6 × 3 = 3
After interchanging the symbol
→ 15 ÷ 5 × 2 − 6 + 3 = 3
→ 3 × 2 − 6 + 3 = 3
→ 6 − 6 + 3 = 3
→ 3 = 3
Hence, the option A is correct.
15 + 5 − 2 ÷ 6 × 3 = 3
After interchanging the symbol
→ 15 ÷ 5 × 2 − 6 + 3 = 3
→ 3 × 2 − 6 + 3 = 3
→ 6 − 6 + 3 = 3
→ 3 = 3
Hence, the option A is correct.
