Hint: There is a little trick to this puzzle.
12 + 6 + 1 = 19.
Note that the puzzle didn't ask for three digits to be circled!
After a day picking strawberries I had a basket full.
I ate 5 and gave Alex half of the remaining.
I then ate another 3 and gave Blake one third of the remaining.
I ate another 6 and then gave Charlie two thirds of the remaining.
I now had 34 strawberries left. How many did I start with?

Hint: What fraction of the did I eat?
Answer: 335 strawberries.
I ended up with 34 strawberries, so I had 102 before giving Charlie two thirds.
I ate 6 myself, so I had 108 before I ate those.
I had 108 strawberries, so I had 162 before giving Blake one third.
I ate 3 myself, so I had 165 before I ate those.
I had 165 strawberries, so I had 330 before giving Alex one half.
Ate 5 myself, so I had 335 before I ate those.
Therefore I started with 335 strawberries.
