Question

Tina can make a dress in 4 days. Daisy takes 6 days to make the same dress while Paul is very fast and can make the dress in just 2 days. If all of them start working together on the dress, then how much time would be required to complete it?

Answer 1

Dear Student,

◆ Answer -

12/11 day

● Explaination -

Tina makes 1/4th part of dress in a day. Similarly Daisy and Paul make 1/6th and 1/2th part of dress in a day.

Let x be no of days all three take to complete dress.

x×1/4 + x×1/6 + x×1/2 = 1

x × 11/12 = 1

x = 12/11 day

x = 1 day 2 h 11 min

Therefore, all three will take 12/11 days to complete the dress.

Hope that's useful...
