Answer 2

based on the information provided, it is not possible to determine how long it would take Rohan to finish the work alone.

To Find:

• How long it would take Rohan to finish the work alone.

Given:

• Rohit can finish the work in 30 days
• Rohit and Rohan working together can finish the work in 12 days

Solution:

The information provided in the question can be used to determine the rate at which each person can complete the work, but it cannot be used to determine the amount of time it would take for Rohan to complete the work alone. The time it takes for a group of people to complete a task is not necessarily indicative of how long it would take an individual member of that group to complete the task on their own.

For example, if Rohit and Rohan have different skill levels or work at different speeds, then it would not be accurate to assume that Rohan could complete the work in the same amount of time that it takes Rohit and Rohan working together. Additionally, when working together, they may be able to divide the work and work in parallel which speeds up the work, but when working alone, Rohan will not be able to divide the work and will work linearly which will take more time.

So, based on the information provided, it is not possible to determine how long it would take Rohan to finish the work alone.
