Options
- A+ and −&
- B÷ and ×
- C+ and ÷
- D− and ÷
Correct answer
D. − and ÷
Step-by-step solution
From the option fourth, we get
64 − 8 × 9 ÷ 8 = 64
Putting (− & ÷) in the equation,
→ 64 ÷ 8 × 9 − 8 = 64
→ 8 × 9 − 8 = 64
→ 72 − 8 = 64
→ 64 = 64
Hence, the option D is correct.
64 − 8 × 9 ÷ 8 = 64
Putting (− & ÷) in the equation,
→ 64 ÷ 8 × 9 − 8 = 64
→ 8 × 9 − 8 = 64
→ 72 − 8 = 64
→ 64 = 64
Hence, the option D is correct.
