Correct option is B
Using the BODMAS rule. The BODMAS rule stands for:
B – Brackets, O - Orders (i.e., powers and roots, etc.), D – Division, M – Multiplication, A – Addition, S - Subtraction
Option (a): Interchanging '-' and '='
Equation becomes:
10 = 3+2×12÷6−6
10 = 3+2×2−6
10 = 3+4−6
10 = 7 - 6
10 ≠ 1
it does not match the options given for valid answers.
Option (b): Interchanging '×' and '+'
10−3×2+12÷6 = 6
10−3×2 +2= 6
10−6+2= 6
10−4 = 6
6 =6 The equation is correct.
Option (c): Interchanging '=' and '+'
Equation becomes:
10−3 = 2×12÷6+6
7 = 2×2+6
7 = 4+6
7 ≠ 10, which is not correct.
Option (d): Interchanging '+' and '-'
10+3−2×12÷6 = 6
10+3−2×2 =6
10+3−4 =6
13−4= 6
9 ≠ 6
Which is not correct.
Hence, option (b) is the correct
