BODMAS Table:
Let's check each option one by one.
Option 1) + × -
Given: 5 * 0 * 3 * 5
After replacing the * signs we get;
⇒ 5 + 0 × 3 - 5 = 20
⇒ 5 + 0 - 5 = 20
⇒ 5 - 5 = 20
⇒ 0 ≠ 20
⇒ LHS ≠ RHS
Option 2) - + ×
Given: 5 * 0 * 3 * 5
After replacing the * signs we get;
⇒ 5 - 0 + 3 × 5 = 20
⇒ 5 - 0 + 15 = 20
⇒ 20 - 0 = 20
⇒ 20 = 20
⇒ LHS = RHS
Option 3) × + -
Given: 5 * 0 * 3 * 5
After replacing the * signs we get;
⇒ 5 × 0 + 3 - 5 = 20
⇒ 0 + 3 - 5 = 20
⇒ 3 - 5 = 20
⇒ -2 ≠ 20
⇒ LHS ≠ RHS
Option 4) + - ×
Given: 5 * 0 * 3 * 5
After replacing the * signs we get;
⇒ 5 + 0 - 3 × 5 = 20
⇒ 5 + 0 - 15 = 20
⇒ 5 - 15 = 20
⇒ -10 ≠ 20
⇒ LHS ≠ RHS
Hence, the correct answer is "Option 2".
