Interchanging the given two numbers and find which the following equation will not correct.
Let's check each option one by one.
Option 1) 4 × 3 - 8 ÷ 2 + 7 = 11
Given: 4 and 2
⇒ 2 × 3 - 8 ÷ 4 + 7 = 11
⇒ 2 × 3 - 2 + 7 = 11
⇒ 6 - 2 + 7 = 11
⇒ 13 - 2 = 11
⇒ 11 = 11
Option 2) 8 ÷ 4 × 2 - 6 + 9 = 18
Given: 4 and 2
⇒ 8 ÷ 2 × 4 - 6 + 9 = 18
⇒ 4 × 4 - 6 + 9 = 18
⇒ 16 - 6 + 9 = 18
⇒ 25 - 6 = 18
⇒ 19 ≠ 18
Option 3) 4 - 8 × 3 + 2 ÷ 1 = –18
Given: 4 and 2
⇒ 2 - 8 × 3 + 4 ÷ 1 = –18
⇒ 2 - 8 × 3 + 4 = - 18
⇒ 2 - 24 + 4 = - 18
⇒ 6 - 24 = - 18
⇒ - 18 = - 18
Option 4) 6 × 4 - 8 ÷ 2 + 7 = 17
Given: 4 and 2
⇒ 6 × 2 - 8 ÷ 4 + 7 = 17
⇒ 6 × 2 - 2 + 7 = 17
⇒ 12 - 2 + 7 = 17
⇒ 19 - 2 = 17
⇒ 17 = 17
Hence, the correct answer is "Option 2".
