We have to find after interchanging the given two signs and numbers which of the following equation will be correct.
Given: + and –, 6 and 3
Let's check each option one by one.
Option 1) 8 – 3 × 4 ÷ 6 + 9 = 18
Given: + and –, 6 and 3
After interchanging the given two signs and numbers we get the;
⇒ 8 + 6 × 4 ÷ 3 - 9 = 18
⇒ 8 + 6 × 1.33 - 9 = 18
⇒ 8 + 8 - 9 = 18
⇒ 16 - 9 = 18
⇒ 7 ≠ 18
⇒ LHS ≠ RHS
Option 2) 8 + 4 × 6 ÷ 3 – 9 = 15
Given: + and –, 6 and 3
After interchanging the given two signs and numbers we get the;
⇒ 8 - 4 × 3 ÷ 6 + 9 = 15
⇒ 8 - 4 × 0.5 + 9 = 15
⇒ 8 - 2 + 9 = 15
⇒ 17 - 2 = 15
⇒ 15 = 15
⇒ LHS = RHS
Option 3) 9 ÷ 3 × 4 – 6 + 7 = 10
Given: + and –, 6 and 3
After interchanging the given two signs and numbers we get the;
⇒ 9 ÷ 6 × 4 + 3 - 7 = 10
⇒ 1.5 × 4 + 3 - 7 = 10
⇒ 6 + 3 - 7 = 10
⇒ 9 - 7 = 10
⇒ 2 ≠ 10
⇒ LHS ≠ RHS
Option 4) 6 ÷ 2 × 8 + 3 – 1 = 20
Given: + and –, 6 and 3
After interchanging the given two signs and numbers we get the;
⇒ 3 ÷ 2 × 8 - 6 + 1 = 20
⇒ 1.5 × 8 - 6 + 1 = 20
⇒ 12 - 6 + 1 = 20
⇒ 13 - 6 = 20
⇒ 7 ≠ 20
⇒ LHS ≠ RHS
Hence, the correct answer is "Option 2".
