Forget conventional ways of solving math questions. In DS, Variable approach is the easiest and quickest way to find the answer without actually solving the problem. Remember equal number of variables and independent equations ensures a solution.
We can assume 2 variables and 1 equation. Thus C could be the answer most likely.
Condition 1)\(a = 12\)
This condition alone is
