According to the question, after interchanging the signs:
Option 1) ×, +, =
15∗4∗10∗50 ⇒ 15 × 4 + 10 = 50
⇒ 15 × 4 + 10 = 50
⇒ 60 + 10 = 50
⇒ 70 ≠ 50 (LHS ≠ RHS)
Option 2) -, ×, =
15∗4∗10∗50 ⇒ 15 - 4 × 10 = 50
⇒ 15 - 4 × 10 = 50
⇒ 15 - 40 = 50
⇒ -25 ≠ 50 (LHS ≠ RHS)
Option 3) ×, -, =
15∗4∗10∗50 ⇒ 15 × 4 - 10 = 50
⇒ 15 × 4 - 10 = 50
⇒ 60 - 10 = 50
⇒ 50 = 50 (LHS = RHS)
Option 4) +, ×, =
15∗4∗10∗50 ⇒ 15 + 4 × 10 = 50
⇒ 15 + 4 × 10 = 50
⇒ 15 + 40 = 50
⇒ 55 ≠ 50 (LHS ≠ RHS)
Hence, "Option 3" is the correct answer.
