The description for doing the 1 job indicates that the one-man work rate is job per day. The added 15 more men mean that the rate simply doubles.

Let t be the additional days that the 30 men work together.

100 additional days for the 15 EXTRA MEN (meaning 30 men total) to FINISH after the first ten days.
