Correct option is B
The correct answer is (B) 5 + 1 / 4 - 3 = 19.
1. Decoding the Rules
Based on the examples provided, the operators have been swapped as follows:
+ means - (Example: 5 + 2 = 3)
- means + (Example: 5 - 2 = 7)
/ (division) means x (multiplication) (Example: 10 / 2 = 20)
x (multiplication) means / (division) (Example: 10 x 2 = 5)
Crucial Rule: Calculate strictly from left to right, ignoring BODMAS.
2. Testing the Options
Option 1: 9 x 3 - 1 / 2 = 18
Transformed: 9 / 3 + 1 x 2
Left-to-Right: 9 / 3 = 3; 3 + 1 = 4; 4 x 2 = 8 (Incorrect)
Option 2: 5 + 1 / 4 - 3 = 19
Transformed: 5 - 1 x 4 + 3
Left-to-Right: 5 - 1 = 4; 4 x 4 = 16; 16 + 3 = 19 (Correct)
Option 3: 6 x 2 - 1 + 2 = 12
Transformed: 6 / 2 + 1 - 2
Left-to-Right: 6 / 2 = 3; 3 + 1 = 4; 4 - 2 = 2 (Incorrect)
Option 4: 7 / 2 + 4 - 2 = 14
Transformed: 7 x 2 - 4 + 2
Left-to-Right: 7 x 2 = 14; 14 - 4 = 10; 10 + 2 = 12 (Incorrect)
