Interchanging the given two numbers to find which of the following equation will be correct.
Let's check each option one by one:
Option 1) 9 × 3 – 4 ÷ 2 + 1 = 10
Given: 1 and 9
After interchanging the numbers we get the:
⇒ 1 × 3 – 4 ÷ 2 + 9 = 10
⇒ 1 × 3 - 2 + 9 = 10
⇒ 3 - 2 + 9 = 10
⇒ 12 - 2 = 10
⇒ 10 = 10
⇒ LHS = RHS
Option 2) 1 + 9 × 3 – 4 ÷ 2 = 18
Given: 1 and 9
After interchanging the numbers we get the:
⇒ 9 + 1 × 3 – 4 ÷ 2 = 18
⇒ 9 + 1 × 3 - 2 = 18
⇒ 9 + 3 - 2 = 18
⇒ 12 - 2 = 18
⇒ 10 ≠ 18
⇒ LHS ≠ RHS
Option 3) 9 × 2 + 1 – 8 ÷ 4 = 12
Given: 1 and 9
After interchanging the numbers we get the:
⇒ 1 × 2 + 9 – 8 ÷ 4 = 12
⇒ 1 × 2 + 9 - 2 = 12
⇒ 2 + 9 - 2 = 12
⇒ 11 - 2 = 12
⇒ 9 ≠ 12
⇒ LHS ≠ RHS
Option 4) 9 – 1 + 6 ÷ 2 × 3 = 7
Given: 1 and 9
After interchanging the numbers we get the:
⇒ 1 – 9 + 6 ÷ 2 × 3 = 7
⇒ 1 - 9 + 3 × 3 = 7
⇒ 1 - 9 + 9 = 7
⇒ 10 - 9 = 7
⇒ 1 ≠ 7
⇒ LHS ≠ RHS
Hence, the correct answer is "Option 1".
