Answers
Step-by-step explanation:
Let "60 units" represent the work done.
1) Find how many units Puru can do in 1 day.
60 units / 14 days = 4.28571428571
Puru can do 4.28571428571 units a day.
2) Find how many units Krisha can do in 1 day.
60 units / 11 days = 5.45454545455
Krisha can do 5.45454545455 units a day.
3) Find how many units Puru and Krisha can do together in 1 day.
4.28571428571 + 5.45454545455 = 9.74025974026
Together, Puru and Krisha can do 9.74025974026 units a day.
4) Find how many days will they finish the work together.
60 units / 9.74025974026 units = 6.16
Because we are dealing with days the answer should not have a remainder.
Answer:
Together, Puru and Krisha can complete the work in 6 days 9 minutes and 36 seconds.
