Heard this one the other day. No pencil or paper allowed. And it's NOT a trick (can't have half a hole etc)

Anyway - -

If a man and a half dig a hole and a half in a day and a half how many holes does one man dig in a week?

not fair if you can have half a hole in the question and can't have half a hole in the answer ðŸ˜›

1,5 - 1,5 - 1,5

1 - 1 - 1,5

1 - 2 - 3

1 - 2/3 - 1

1 - 14/3 - 7

So one man digs 4,7 holes in 7 days.

Yes - basically it's 4 and 2/3rds.
It was explained to me that it takes a day and a half to dig a hole and a half - therefore a hole a day.

Simple after that
