Month Jan Feb March April May June

Number of vehicles sold 300 250 400 100 150 350

Represent the above data by a pictograph. January

Solution: The above data can be represented by a pictograph as February
given below:
March
In this pictograph the picture symbol represents 100

vehicles. As we have seen that this way of representing April
numerical data is time consuming and sometimes we May
have to draw part picture symbol which is also a difficult
task. So, it is not very useful. June
