**A man buys a horse for $60. He sells it for $70.**

**He then buys the horse back for $80. And he sells the horse for $90.**

**In the end, how much money did the man make or lose? Or did he break even?**

**How to solve the brain teaser that’s stumping the internet**

First, subtract $70 from $60 as the man-made a $10 profit when he sold the horse for $10 more than he bought it.

Next, subtract $80 from $90 because the man-made another $10 profit when he sold the horse again.

So the problem would look like:

70-60=10 and 90-80=10

And 10 plus 10 equals 20 which how much the man profited from the horse.

**Peerie Breeks, who shared the brain teaser wrote on the website: ‘Can’t understand how so many people on Facebook have it so completely wrong (and can justify it to themselves).’**

‘Without adding your reasoning, tell me what you think the answer is.’

But the teaser has left Facebook users more confused than ever with answers varying in the price of how much money he made.

One Facebook user said: ‘Actually it’s even. He sold it for 70 but had to put another 10 in to buy it 80. Sold it for 90 made 10 but put in 10 to buy it back at 80.’

Wrong: One man shared on Facebook that he didn’t understand how people were getting $20.

Another disagreed and instead of thinking the man broke even, though he was down $40.

She said: ‘The man is down $40. Did we forget the original $60 he spent?’

For those that are curious, the man-made a $20 profit when he bought and then sold the horse but the answer wasn’t so easy to come by for some people.

One man shared on Facebook: ‘I don’t understand how people are coming up with up 20.’

And after trying multiple times to solve the problem, he added: ‘Up 10, even, then up 10 is what I got!?’

But in order to put any confusion to rest, someone explained the problem in a comment on Facebook.

He said: ‘He buys a horse for $60. Sells for $70. Put that $10 aside. Buys the horse for $80. Sells it for $90. Another $10 profit.’

This isn’t the first time a seemingly easy puzzle has baffled the internet.
