Of the 60, 45 are men and 24 are blonde.
At least 9 of the men have to be blonde. Why?
If all women were blonde, that means there are 15 blonde women. You know there are 24 total blondes, so 9 of the men must also be.
60-45=15
24-15=9
If I may add, it's wrong that you're being home-schooled by people who are clearly unqualified. How could a teacher not be able to answer such a simple question?

No of men=3/4 of 60=45
No of people having blonde hair=2/5 of 60=24No.of women in the room=60-45=15.
If all the women have blonde hair at least 24-15 or 9 men must have blonde hair

1/4 of 60 is 15. That's how many woman there are. If all the women are blond, there will be the least amount possible of blond men.
2/5 of 60 is 24. That's the number of blond people. If 15 are women and they are all blond, that leaves 9 blond men...I think.

60 (people total) x .75 (% of men in the room) = 45 men in the room
60 x .4 (2/5 of blond people in the room) =24 blond people in the room
60-45= 15 ("other" people in the room)
24(blond people in the room) -15(other people in the room)=9 (least # of blond men in ther room)
24 is the # of the most blond ppl in the room were 15 is the other ppl in the room wihich leaves us with only 9 ppl left that could be blond and not anything other than men.
Hope this helps!

This means 45 of the people are men, and 15 are women. 24 have blonde hair. So if all of the women have blonde hair, only 9 men do. That's the fewest possible.

The LEAST number of men in the room who could have blonde hair would either 0 or 1 depending on how you look at it.
The MOST that could have blonde hair would be 27?
Oops, did the % the wrong way - the MOST would be 18.

I come up with 18
2/5 of 60 is 24
3/4 ( # of men) of 24
18
If you assume ALL THE WOMAN ARE BLONDES 9 is correct

This is what's wrong with home schooling! If you were at school you'd be able to work this out with a teacher. Why are your parents letting you be schooled by a computer anyway!?
