Neha is manufacturing plastic lunch boxes for a job. She got a project to manufacture some boxes, out of which she completed \(\frac{{15}}{{23}}\) of the project in 30 days. In how many days did she complete the entire project for the company?
46
The correct answer is 46.
This means the amount of work done per unit of time (like per day) remains the same throughout the project. In this problem, since Neha completes \frac{15}{23} of the project in 30 days, her daily work rate is constant. This confirms the result obtained using the direct proportion method. This type of problem is common in competitive exams and helps build a foundation for more complex work and time problems involving multiple people or changing work rates.
