Question 13

Solve the equation. 
A) 
B) 
C) 
D) 
E)

Accepted Answer

There is no clear method to solve the equation since there are no given variables or operations. Therefore, the answer cannot be found by mathematical calculation. Each choice appears to be a random combination of letters and numbers. The only way to find the answer is by guessing or by having additional information not provided in the question. However, choice C is the only one that differs by only one character from choice A, which might hint that it is the correct answer.
