Option 1 : 48 N 4 C 2 B 5 O 10 B 2 C 4 Y 53
1) By substituting the above signs we get,
Equation: 48 N 4 C 2 B 5 O 10 B 2 C 4 Y 53
48 + 4 ÷ 2 × 5 – 10 × 2 ÷ 4 = 53
53 = 53
2) By substituting the above signs we get,
Equation: 24 C 2 B 4 N 2 C 2 B 3 N 16 Y 70
24 ÷ 2 × 4 + 2 ÷ 2 × 3 + 16 = 70
67 ≠ 70
It should be 67 but it is given 70, thus it is the incorrect equation.
3) By substituting the above signs we get,
Equation: 25 B 5 O 5 N 10 C 5 B 2 C 4 Y 119
25 × 5 – 5 + 10 ÷ 5 × 2 ÷ 4 = 119
121 ≠ 119
It should be 121 but it is given 119, thus it is the incorrect equation.
4) By substituting the above signs we get,
Equation: 70 O 4 B 2 N 15 C 5 N 15 0 10 Y 72
70 – 4 × 2 + 15 ÷ 5 + 15 – 10 =
70 ≠ 72
It should be 70 but it is given 72 thus it is the incorrect equation.
Hence, answer is equation 1.
