A alone can finish a piece of work in 12 days and B alone can do it in...
A can finish the work in 12 days.
B can finish the work in 18 days.
∴ Ratio of their one-day work = 1/12 : 1/18 = 3 : 2
∴ If they work together and finish the work, they get the assigned amount in the ratio 3 : 2. That is, A will get Rs. 30 and B will get Rs. 20 (∵ total amount = Rs. 50).

A alone can finish a piece of work in 12 days and B alone can do it in...
To solve this problem, we need to find the individual rates at which A and B work and then use those rates to determine the portion of the work completed by each person. Based on that, we can calculate their respective wages.

Given:
- A can finish the work in 12 days
- B can finish the work in 18 days

Let's start by calculating their individual work rates.

Calculating Work Rates:
- A's work rate = 1/12 (as A can finish the work in 12 days)
- B's work rate = 1/18 (as B can finish the work in 18 days)

Now, let's determine their combined work rate when they work together.

Calculating Combined Work Rate:
- Combined work rate = A's work rate + B's work rate
= 1/12 + 1/18
= 5/36

This means that when A and B work together, their combined work rate is 5/36 of the total work per day.

Calculating Portion of Work Completed:
Now, let's determine the portion of the work completed by each person when they work together.

- A's portion of work completed = A's work rate / Combined work rate
= (1/12) / (5/36)
= 3/5

- B's portion of work completed = B's work rate / Combined work rate
= (1/18) / (5/36)
= 2/5

This means that when A and B work together, A completes 3/5 of the work and B completes 2/5 of the work.

Calculating Wages:
Next, we can calculate their respective wages based on the portion of work completed.

- A's wages = (A's portion of work completed) * (Total wages)
= (3/5) * Rs. 50
= Rs. 30

- B's wages = (B's portion of work completed) * (Total wages)
= (2/5) * Rs. 50
= Rs. 20

Therefore, A will get Rs. 30 out of the total wages of Rs. 50.

Hence, the correct answer is option 'B' (Rs. 30).
