D. Rs 360

Answer

To solve the problem step by step, we will use the concept of work and earnings.

### Step 1: Understand the given information
We know that:
- 15 laborers earn Rs. 1800 in 10 days.

### Step 2: Calculate the earning of 1 laborer in 10 days
To find out how much one laborer earns in 10 days, we divide the total earnings by the number of laborers:
\[ \text{Earning of 1 laborer in 10 days} = \frac{1800}{15} = 120 \text{ Rs.} \]

### Step 3: Calculate the earning of 1 laborer in 1 day
Now, we need to find out how much one laborer earns in one day:
\[ \text{Earning of 1 laborer in 1 day} = \frac{120}{10} = 12 \text{ Rs.} \]

### Step 4: Calculate the earning of 5 laborers in 1 day
Next, we calculate how much 5 laborers earn in one day:
\[ \text{Earning of 5 laborers in 1 day} = 5 \times 12 = 60 \text{ Rs.} \]

### Step 5: Calculate the earning of 5 laborers in 8 days
Finally, we calculate how much 5 laborers will earn in 8 days:
\[ \text{Earning of 5 laborers in 8 days} = 60 \times 8 = 480 \text{ Rs.} \]

### Conclusion
Thus, the earning of 5 laborers in 8 days will be Rs. 480.
