Time and Work Practice Test 1 with solutions

Question : 40 of 40

Marks: +1, -0

Drishti completed her assignment in

37 1/2

days whereas Payal completed the same assignment in 25 days. Find the time taken by them to complete both the assignments working together.

Solution:

Work done by Drishti in one day =

2/{75}

Work done by Payal in one day =

1/{25}

Work done by both in one day =

2/{75}+1/{25}

1/{15}

So, time taken by both of them to complete one assignment = 15 days
Time taken by them to complete two assignments = 30 days.
