Chapter 4: Algebra Puzzle

1) First , i saw that the middle column was the easiest to solve as all the shapes were the same , thus i      divided 39 by 3.
This gave me 13 , thus 13 was a umbrella.
2) Next, i saw that the top row had only one umbrella and the other shapes were the same. Thus , i minus-ed 13 from 37 to give me 2 ice creams.
3) 2 ice creams were 24 and i simply divided it by 2 , giving me 1 ice cream which equalled to 12.
4) Finally , i used the first column and minus-ed two umbrellas from 25 which gave me one pear. This was how i found out my answer.
