Write the number of chocolate donuts sold.

The correct answer is: 4

Now we know that a pictograph often referred to as a pictograph in mathematics, is a visual representation of data that uses pictures, icons, or other symbols. Using a pictograph, we can depict the frequency of data using pertinent symbols or images. One of the simplest methods for representing data is through pictographs.
Key is always used to indicate the symbol's value.
While solving questions related to pictographs, we should keep these points in mind:

• The size of each sign or image must be uniform.
• Additionally, data can be displayed using a portion of an icon.

Now we have given a pictograph. In that graph, there are 6 categories, Sprinkles, custard, original, chocolate, frosting and Jelly. We have asked how many number of chocolate donuts are sold.
So from the pictograph, we can see that the custard category is having a maximum key which is 10.
So 10 chocolate donuts were sold.

4 number of chocolate donuts are sold.

Here we used the concept of pictographs. Although they are incredibly convenient and should be utilised properly, pictographs may result in incorrect data interpretation. So 4 number of chocolate donuts are sold. For representing a huge amount of data, pictographic representation can be helpful.
