This is ambiguous. I will take as t days with 10 workers, and 35-t days with the remaining 5 workers. This makes for a total job time of 35 days from start to finish.

, accounts for "one whole work".

Look at first sentence.
Let r be rate for one worker, jobs per days.

.

Use the needed data in the work-rates rule.

If this makes sense, and especially if you can formulate the equation on your own, then enough help done; just solve for t.
