Given equation: 4 + 6 × 7 - 27 ÷ 3 = 7 × 8 - 4 + 39 ÷ 3 Check the options Option 1: 3, 4 After interchanging the equation becomes; ⇒ 3 + 6 × 7 - 27 ÷ 4 = 7 × 8 - 3 + 39 ÷ 4 ⇒ 38.25 is not equal to 68.25. Hence, option 1 is not the correct answer. |

Option 2: 6, 8 After interchanging the equation becomes; ⇒ 4 + 8 × 7 - 27 ÷ 3 = 7 × 6 - 4 + 39 ÷ 3 ⇒ 51 = 51 Since we got our answer, we don't need to check other options. Hence, option 2 is the correct answer. |
