Answer:

C. 30

Step-by-step explanation:

15 men do work in 16 days

This means that 7.5 men (15/2) would do that same work in 32 days (16x2).

If the number of men increase, the amount of days decrease.

8 men would do that work in 30 days

8 men > 7.5 men

30 days < 32 days

Option c.

Step-by-step explanation:

It is an inverse proportion, fewer workers more days to finish the job.

15 -----16

8 ----- x

x = (16)(15)/8 = 240/8 = 30 days
