B Correct answer
Explanation

Work ratio A:B = (1/12):(1/10) = 5:6. A's share = 5/11 * 330 = 150.

AI explanation

Using the LCM method, the total work is 60 units, where A's efficiency is 5 units per day and B's efficiency is 6 units per day. The wages are distributed in proportion to the work done, so the ratio of their shares is 5 to 6. A's share is calculated as 5 divided by 11, multiplied by Rs. 330, which equals Rs. 150.
