1. On which day of the week did Mr Brown sell the maximum ice creams? Draw a pictograph.
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)
ILLUSTRATIVE EXAMPLES Now we may draw the pictograph as shown below.

EXAMPIE: 1 The number of cricket bats sold by a shop during a week are given below. Mode Number of students

Day Monday Tuesday Wednesday Thursday Friday Saturday Walking

No. of 20 12 24 32 8 16 Using bicycles

Using Cars

Draw a pictograph.
Using Bus

SOLUTION Scale, = 4 bats sold
EXAMPLE:3 The following pictograph shows the number of computers sold by a company
Now, we may draw the pictograph, as shown below. during a week.
The scale used: = 6 computers
Day No. of bats sold

EXAMPLE: 2 The modes of travelling to school by 160 students are given below: (i} Number of computers sold on Friday= ( 4 × 6) = 24.
(ii) Number of computers sold on Monday= (5 × 6) = 30.
(iii) Number of computers sold during the week
Mode = [(5 + 3 + 2 + 6 + 4 + 1) × 6) = (21 × 6) = 126.
