A man buys a goat for $60.
Then he sells it for $70.
Then he buys it back for $80
And sells it again for $90
How much profit did he make?
Mmmmm, I wonder?
No Googling or asking a nearby child....

I'm going to go with the obvious and say $30.

Sorry but I couldn't help breaking the rule. My grand daughter says you must need a calculator.

Seems to me he spent a total of $140 and received a total of $160, so the profit is $20

I believe that he made $20, purchases $60 plus $80 = $14, sales $70 plus $90 = $160. Look at it another way, he made a profit of $10 out of each of the two transactions. Think of it as being two separate goats.

$20
lets say he started with 100$
100-60 (buys the goat)
=$40+goat
40+70(sells the goat)
=$110
110-80(buys the goat again)
=$30+goat
30+90(sell the goat again)
=$120
From $100, he earned a profit of $20

]A man buys a goat for $60.
Then he sells it for $70. (Gain )$10)
Then he buys it back for $80 (Loss $10, he is breaking even.)
And sells it again for $90 (Gain $10)
By this calculation $10 profit, or he originally bought it for $60 and finally sold it for $90 for a $30 profit.
I need to go to bed my brain hurts.
