Pictograph
Representing data using pictures is called pictograph. A pictograph always has a title and
a key explaining what each picture stands for.

Example 2: Shreya bought a bouquet with a variety of flowers in it. The following
pictograph shows the different types of flowers in the bouquet.

Flower Number of Flowers

Lily

Pink rose
= 3 flowers
Orchid

Carnation

Tulip

Read the pictograph carefully and answer the following questions.

(a) How many lilies are there in the bouquet?
(b) Which flower is used the most in the bouquet?

(c) How many more pink roses are there than tulips?
(d) Arrange the names of the flowers in increasing order of their numbers.

(e) How many flowers are there in the bouquet?

Solution: (a) Number of lilies = 4 × 3 = 12 (each stands for 3 flowers)
(b) Pink roses are used the most in the bouquet.

(c) Number of pink roses = 9 × 3 = 27
Number of tulips = 5 × 3 = 15

So, there are 27 – 15 = 12 pink roses more than tulips.

(d) Lilies < tulips < carnations < orchids < pink roses
(e) Number of lilies = 4 × 3 = 12

Number of pink roses = 9 × 3 = 27
Number of orchids = 7 × 3 = 21

Number of carnations = 6 × 3 = 18

Number of tulips = 5 × 3 = 15
Total number of flowers = 12 + 27 + 21 + 18 + 15 = 93

So, there are 93 flowers in the bouquet.
