OSTRICHES
Two ostrich breeders, Mandy and Marcia, were talking one day, and noticed that if Mandy sold Marcia seven ostriches, Mandy would have exactly as many ostriches as Marcia.
On the other hand, if Marcia sold Mandy seven ostriches, then Mandy would have exactly twice as many ostriches as Marcia. How many ostriches did each have?
Answer

What exactly do you mean by that? This is a perfectly fine teaser.
I enjoyed this teaser. I like having fun as I learn. Thanks
Good one dodger I like these a lot, keep them coming
I love this type of teaser too....keep them coming Dodger
This isn't a duplicate as far as i'm concerned. Great one Dodger. Keep up the cool work.
Yes, it is a fine teaser.
I'm sorry, but the FAQ says:
"Sometimes teasers are not exact duplicates, but are close enough that they seem like the same puzzle. For example if you have one teaser about the probability of picking certain color balls out of a box, and another teaser about picking different types of fruits out of a basket. It is likely that this will be considered to be a duplicate if the rest of the teaser is the same. "
So, compare to teaser #1955...?

I UNDERSTAND THE CONCEPT OF DUPLICATION, HOWEVER I STILL THINK MY TEASER IS INDIVIDUAL ENOUGH TO BE CONSIDERED WORTHWHILE ON IT'S OWN MERIT. EVERYONE ELSE SEEMS TO LIKE IT.

Thanx, i really appreciate it.
This is not a duplicate.
Oh, sorry. Then does it mean that I can submit more 7:5 teasers, such as 777:555 or 999999:714285, and get accepted?

I'm not even gonna try, I just failed at one a minute ago with almost the exact same story.
top teaser, failed miserably though!!
mr. shengiang, a lot of math brain teasers follow a certain pattern (formula, if you will), but they're fun & educational all the same. i loved this one.
Got it after some thinking... Keep it up Romeo!
