You need to work out the averagethat each worker can dig per day.
10 workers dig 5 holes in 2 days, so 5 workers dig 5 holes in double the time, i.e: 4 days. If it takes 5 workers 4 days to dig 5 holes, then it will take them 8 days to dig 10 holes. Does that makes sense?

number of workers halved, no. of days 5 times, so overall 2.5*5

Ignore the first sentence, I used a different method.

klimenkov · Answer

10 workers will dig 25 holes in 10 days. 5 workers will dig a half of their holes = 12.5

Sorry, just realised I was working out days and not holes lol... Read the question properly!
The correct method is:
10 workers dig 5 holes in 2 days.
Then 5 workers dig 2.5 holes in 2 days.
Then 5 workers dig $5\times 2.5$ holes = 12.5 holes (12 complete holes) in 10 days.
