B Correct answer
Explanation

Wages are divided in the ratio of work done. A does 1/12 per day, B does 1/18 per day. Ratio of work is 1/12 : 1/18 = 3:2. A's share = (3/5) * 50 = 30.

AI explanation

A's one day work is 1/12 and B's one day work is 1/18, so their efficiency ratio is 18:12 or 3:2. The total wages of Rs. 50 are divided in this ratio, meaning A receives (3/5) of the total amount. Multiplying 50 by 3/5 gives Rs. 30.
