Question: Starting on February 25, 1996, if Raja had finished his job on April 2, 1996, when would T and S together likely to have completed the job, had they started on the same day as Raja?
Now Raja has worked for (5 days in February + 31 days in March + 2 days in April) = 38 days. Let us assume his rate to be the same as in the previous question, viz. one unit a day. Hence, he completes 38 units totally. In a week, T takes holiday on Tuesday and Thursday, while S takes holiday on Saturday and Sunday. We can see that their working pattern would be as follows.
So in a week they work together 10 units work. Thus, in three weeks, they would complete 30 units work. It
can be found out that February 25 is Sunday. So the remaining 8 units of work can be completed only on Friday, i.e. March 22.
