        2.     On which day of the week did Mr Brown sell the least number of ice creams?                                          SOLUTION             Let us choose the  scale as given below:
               Pictograph                                                                                                                                      = 10 students (walking)
        An information regarding the number of certain things can be nicely conveyed through pictures. PICTOGRAPH                                              = 10 students (using bicycles)
        The representation of an information through pictures is called a pictograph.                                                                         = 10 students (using car)
                                                                                                                                                        q      = 10 students (using car)
