To think that this sum is super simple

and 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.

£20- easy peasy

Made 20 but 10 profit? My maths is shockingly bad.

Beckyb1 · 11/02/2018 08:37

10 up

BookHelpPlease · 11/02/2018 08:37

he spent 60+80 = 140.
He made 70+90 =160
difference is =20

The first transaction he made $10, then he was down $10 when he bought back at a loss, then he sold again for $10 profit which wiped out the $10 loss so all in all he broke even in my book

MysweetAudrina · 11/02/2018 08:38

Has to be 20.

ManagedTeaCups · 11/02/2018 08:38

I though 10 profit at the end but not sure nlw

UnimaginativeNameChange1 · 11/02/2018 08:38

He spends a total of $140 and 'earns' a total of $160. $20 difference.

DadDadDad · 11/02/2018 08:39

Ifailed and BookHelpPlease have encapsulated it perfectly. It's definitely $20.

DrRanjsRightEyebrow · 11/02/2018 08:39

Up 20

BookHelpPlease · 11/02/2018 08:39

Ladies the first transaction is separate from the first. He makes 10 on each transaction. So he makes 20 in total.

Emabrmsca · 11/02/2018 08:39

Just done it on a calculator and will change my answer to say he's up $20

My maths is awful!!

I know it's $20. But there are people saying anything from break even to $40 profit.

Some of the ones that are wrong are telling the period that are right that they shouldn't run a business of that's how they calculate profit! It's highly amusing.

He paid $60 for the horse, and sold it at the end for $90. $30 profit. I think Confused

BookHelpPlease · 11/02/2018 08:40

People on Facebook do tend to be spanners though!

Windmyonlyfriend · 11/02/2018 08:41

Ha! I’ve pondered it further and I’m changing my answer to $20.

Though I can see why these are confusing!

He's only made $10

Pompom42 · 11/02/2018 08:43

Up $20?

CecilyP · 11/02/2018 08:44

Would it hel those who got it wrong to think of it as 2 different horses?

Believeitornot · 11/02/2018 08:44

$20

If you imagine you had $200 in your hand while making these transactions, how much would you end up with afterwards? (I chose $200 at random, could be anything as long as you’ve got enough to buy the most expensive horse).

That’s your profit.

I came out at he broke even...

Danglingmod · 11/02/2018 08:47

Of course it's 20.

CuriousaboutSamphire · 11/02/2018 08:47

Yes, separate transactions. He made a $10 profit on each.

Or he spent 60 + 80 = $140
But sold for 70 + 90 = $160

Or any other variation you may prefer.
