Given:
⇒
(1) ÷, ×, -, =, ×
After putting the signs:
⇒ 45 ÷ 9 × 3 - 25 = 55 × 15
Apply BODMAS rule:
⇒ 5 × 3 - 25 = 55 × 15
⇒ 15 - 25 = 825
⇒ (-10) = 825
Here, the equation is not satisfied.
(2) ÷, ×, =, +, +
After putting the signs:
⇒ 45 ÷ 9 × 3 = 25 + 55 + 15
Apply BODMAS rule:
⇒ 5 × 3 = 25 + 55 + 15
⇒ 15 = 95
Here, the equation is not satisfied.
(3) +, =, ÷, ×, +
After putting the signs:
⇒ 45 + 9 = 3 ÷ 25 × 55 + 15
Apply BODMAS rule:
⇒ 54 = 0.12 × 55 + 15
⇒ 54 = 6.6 + 15
⇒ 54 = 21.6
Here, the equation is not satisfied.
(4) ÷, ×, +, =, -
After putting the signs:
⇒ 45 ÷ 9 × 3 + 25 = 55 - 15
Apply BODMAS rule:
⇒ 5 × 3 + 25 = 40
⇒ 15 + 25 = 40
⇒ 40 = 40
Here, the equation is satisfied.
Hence, the correct answer is "Option (4)".
