According to the question, after replacing the signs:
Option 1) + × =
10 * 9 * 6 * 64 ⇒ 10 + 9 × 6 = 64
⇒ 10 + 9 × 6 = 64
⇒ 10 + 54 = 64
⇒ 64 = 64 (LHS = RHS)
Option 2) - × =
10 * 9 * 6 * 64 ⇒ 10 - 9 × 6 = 64
⇒ 10 - 9 × 6 = 64
⇒ 10 - 54 = 64
⇒ -44 ≠ 64 (LHS ≠ RHS)
Option 3) - ÷ =
10 * 9 * 6 * 64 ⇒ 10 - 9 ÷ 6 = 64
⇒ 10 - 9 ÷ 6 = 64
⇒ 10 - 1.5 = 64
⇒ 1.5 ≠ 64 (LHS ≠ RHS)
Option 4) × + =
10 * 9 * 6 * 64 ⇒ 10 × 9 + 6 = 64
⇒ 10 × 9 + 6 = 64
⇒ 90 + 6 = 64
⇒ 96 ≠ 64 (LHS ≠ RHS)
Hence, "Option 1" is the correct answer.
