I think..simply putting the values is the best way to solve this question..
It took me only 10 secs..

40-12= 28.
40/12 = 12 * 3 + 4.

A is the answer..

you are right instead solving we need to see if solving with options is better idea. here otherwise if go through variable and equation formation, it takes more than 2mins.. thanks
