BODMAS table
lets check the option one by one.
Option 1) ÷ and -
Given equation: 6 + 3 × 8 − 12 ÷ 4 = 4
after interchanging the equations we get:
6 + 3 × 8 ÷ 12 - 4 = 4
6 + 2 - 4 = 4
8 - 4 = 4
LHS = RHS
Option 2) + and ÷
Given equation: 6 + 3 × 8 − 12 ÷ 4 = 4
after interchanging the equations we get:
6 ÷ 3 × 8 + 12 - 4 = 4
2 x 8 + 12 - 4 = 4
16 + 12 - 4 = 4
28 - 4 = 4
24 ≠ 4
LHS≠ RHS
Option 3) - and +
Given equation: 6 + 3 × 8 − 12 ÷ 4 = 4
after interchanging the equations we get:
6 ÷ 3 × 8 - 12 + 4 = 4
2 x 8 + 12 - 4 = 4
16 - 12 - 4 = 4
4 - 4 = 4
0 ≠ 4
LHS≠ RHS
Option 4) ÷ and x
Given equation: 6 + 3 × 8 − 12 ÷ 4 = 4
after interchanging the equations we get:
6 x 3 ÷ 8 + 12 - 4 = 4
3 x 3/4 + 12 - 4 = 4
9/4 + 12 - 4 = 4
10.25 ≠ 4
LHS≠ RHS
Hence the correct answer is "Option 1".
