To solve this problem, we'll break down each step and analyze the data:

1. Initial Conditions:
- The total number of drawing notebooks sold is 60.

2. First Batch:
- Number of notebooks sold in the first batch: 20
- Percentage of colored notebooks in the first batch: 20%
- Number of colored notebooks in the first batch: 20% of 20 = 4 colored notebooks

3. Second Batch:
- Number of notebooks sold in the second batch: 30
- Percentage of colored notebooks in the second batch: 40%
- Number of colored notebooks in the second batch: 40% of 30 = 12 colored notebooks

4. Third Batch:
- Number of notebooks sold in the third batch: 10
- Percentage of colored notebooks in the last batch: 80%
- Number of colored notebooks in the last batch: 80% of 10 = 8 colored notebooks

5. Total Colored Notebooks:
- Sum of colored notebooks in all batches: 4 (first batch) + 12 (second batch) + 8 (last batch) = 24 colored notebooks

6. Percentage of Colored Notebooks:
- We need to find what percent of the total 60 notebooks sold were colored.
- Calculation: (Total colored notebooks / Total notebooks sold) 100
- (24 / 60) 100 = 40%

Thus, the percentage of the 60 note books that were in color is 40%.
