Answer: 5:30 PM

Step-by-step explanation:

From 12-3:30, number of minutes = 210 mins

Time which Rajesh takes to complete the work = 5 hrs = 5 x 60 = 300 mins

Rajesh's time allocation will be - 210 mins + 30 mins break + 90 mins post 4 = 5:30 he finishes the work.

Time which Seems takes to complete the work = 90 * (7/3) = 210 mins

Seema's time allocation will be - 210 mins  = 3:30 she finishes the work.

Time which Ramya takes to complete the work = 210 * (4/3) = 280 mins

Ramya's time allocation will be - 210 mins + 30 mins break + 70 mins post 4 = 5:10 she finishes the work.

Work Completed as follows:-

Rajesh - 5:30 PM

Seema - 3:30 PM

Ramya - 5:10 PM

So they all will play together when Rajesh(slowest of all) completes the work. That will be at 5:30 PM.
