Understanding the Problem
To solve the problem, we first need to determine the work rates of Rachna and Perina.
Work Rate of Rachna
- Rachna can complete the work in 16 days.
- Therefore, her work rate is:
- 1 work unit / 16 days = 1/16 of the work per day.
Work Rate of Perina
- Perina completes the same work in half the time taken by Rachna.
- Since Rachna takes 16 days, Perina takes:
- 16 days / 2 = 8 days.
- Hence, Perina's work rate is:
- 1 work unit / 8 days = 1/8 of the work per day.
Combined Work Rate
Now, we will calculate their combined work rate when Rachna and Perina work together.
- Combined work rate = Rachna's work rate + Perina's work rate
- Combined work rate = (1/16 + 1/8)
Finding a Common Denominator
To add these fractions, we need a common denominator:
- The least common multiple of 16 and 8 is 16.
- Convert 1/8 to a fraction with a denominator of 16:
- 1/8 = 2/16
Calculating Combined Rate
- Now add the two fractions:
- 1/16 + 2/16 = 3/16
Conclusion
Thus, when working together, Rachna and Perina can finish:
- 3/16 of the work in one day.
This means that together, they are efficient and can complete a significant portion of the task in a short amount of time.
