Answer

Given Information:
Raju earns Rs 1440 for working 12 days.

To find:
Raju's earnings for 30 days of work.

Solution:
To find Raju's earnings for 30 days of work, we can use the concept of proportionality.

Proportional Relationship:
We can assume that Raju's earnings are directly proportional to the number of days he works. This means that if he works for more days, he will earn more money, and if he works for fewer days, he will earn less money.

Proportion:
Let's set up a proportion to find the answer.

The proportion can be written as:
(days worked) / (earnings) = (days worked) / (earnings)

Using the given information:
12 / 1440 = 30 / x

Cross-multiplying the proportion:
12x = 1440 * 30

Simplifying:
12x = 43200

Dividing both sides by 12:
x = 43200 / 12

Calculating:
x = 3600

Conclusion:
Therefore, if Raju works for 30 days, he will earn Rs 3600. Hence, the correct answer is option 'B': Rs 3600.
