12 × 8 ÷ 36 + 3 – 6 = 102 is to be true. We need to check with the options. |
From option 1, by interchanging signs x and +, we get: 12 + 8 ÷ 36 x 3 – 6 = 102 6.66 ≠ 120 From option 2, by interchanging signs + and -, we get: 12 × 8 ÷ 36 -- 3 + 6 = 102 5.66 ≠ 120 From option 3, by interchanging signs ÷ and x , we get: 12 ÷ 8 x 36 + 3 – 6 = 102 51 ≠ 120 From option 4, by interchanging signs ÷ and +, we get: 12 × 8 + 36 ÷ 3 – 6 = 96 + 12 – 6 = 102 = RHS Hence, Option 4 is correct |
