If 'A' stands for '├╖', 'B' stands for '├Ч', 'C' stands for '+', and 'D' stands for '-', what will come in place of the question mark '?' in the following equation? 144┬аC┬а44┬аD┬а12┬аA┬а12┬аB┬а144=?
54

Substitute the symbols into the equation directly based on the given rules, then apply the BODMAS rule (Bracket, Of, Division, Multiplication, Addition, Subtraction) to evaluate.
Substitute the symbols into the equation directly based on the given rules, then apply the BODMAS rule (Bracket, Of, Division, Multiplication, Addition, Subtraction) to evaluate.
Substitute Symbols
Replace 'C' with '+', 'D' with '-', 'A' with '├╖', and 'B' with '├Ч' in the equation 144 C 44 D 12 A 12 B 144 = ? to get: 144 + 44 - 12 ├╖ 12 ├Ч 144.
Apply BODMAS (Division)
Perform the division operation first: 12 ├╖ 12 = 1. The equation becomes: 144 + 44 - 1 ├Ч 144.
Multiplication & Final Calculation
Perform the multiplication: 1 ├Ч 144 = 144. Then compute addition and subtraction: 144 + 44 - 144 = 188 - 144 = 44.
A: 54 is incorrect because it results from incorrect order of operations or arithmetic error. C: 34 is incorrect because 188 - 144 equals 44, not 34. D: 43 is incorrect due to a calculation error.
B is correct because replacing the symbols according to the given rules and evaluating using BODMAS yields 44.
Always perform division and multiplication before addition and subtraction following the strict BODMAS order of operations to avoid common arithmetic traps.
