Applying the BODMAS rule to the given equations,
1) By substituting the above signs we get,
Equation: 162 N 2 O 2 B 100 C 20 N 2 X 230
162 × 2 ÷ 2 + 100 – 20 × 2 = 230
= 162 × 1 + 100 – 40
= 162 + 60
= 222
= 222 ≠ 230
It should be 222 but it is given as 230, thus it is the incorrect equation.
2) By substituting the above signs we get,
Equation: 36 B 4 O 2 N 5 C 15 B 50 X 81
36 + 4 ÷ 2 × 5 – 15 + 50 = 81
= 36 + 2 × 5 + 35
= 36 + 10 + 35
= 81
It is the correct equation.
3) By substituting the above signs we get,
Equation: 182 O 2 N 4 B 15 C 30 X 351
182 ÷ 2 × 4 + 15 – 30 = 351
= 91 × 4 – 15
= 349
= 349 ≠ 351
It should be 349 but it is given as 351, thus it is the incorrect equation.
4) By substituting the above signs we get,
Equation: 642 O 2 N 3 C 100 B 10 X 875
642 ÷ 2 × 3 – 100 + 10 = 875
= 321 × 3 – 90
= 873
= 873 ≠ 875
It should be 873 but it is given as 875, thus it is the incorrect equation.
Thus, Equation number 2 is correct.
