Select the correct combination of mathematical signs to sequentially replace the * signs and to balance the given equation.

50 * 25 * 10 * 2 * 175

The pattern followed here is:

We have to replace the mathematical signs to sequentially replace the * signs to balance the given equation.

Let's check each option one by one.

Option 1) +, ÷, ×, =

Given: 50 * 25 * 10 * 2 * 175

After putting the mathematical sign we get the;

⇒ 50 + 25 ÷ 10 × 2 = 175

⇒ 50 + 2.5 × 2 = 175

⇒ 50 + 5 = 175

⇒ 55 ≠ 175

⇒ LHS ≠ RHS

Option 2) −, ×, ÷, =

Given: 50 * 25 * 10 * 2 * 175

After putting the mathematical sign we get the;

⇒ 50 - 25 × 10 ÷ 2 = 175

⇒ 50 - 25 × 5 = 175

⇒ 50 - 125 = 175

⇒ - 75 ≠ 175

⇒ LHS ≠ RHS

Option 3) −, ×, +, =

Given: 50 * 25 * 10 * 2 * 175

After putting the mathematical sign we get the;

⇒ 50 - 25 × 10 + 2 = 175

⇒ 50 - 250 + 2 = 175

⇒ 52 - 250 = 175

⇒ - 198 ≠ 175

⇒ LHS ≠ RHS

Option 4) +, ×, ÷, =

Given: 50 * 25 * 10 * 2 * 175

After putting the mathematical sign we get the;

⇒ 50 + 25 × 10 ÷ 2 = 175

⇒ 50 + 25 × 5 = 175

⇒ 50 + 125 = 175

⇒ 175 = 175

⇒ LHS = RHS

Hence, the correct answer is "Option 4".
