How many people were influenced by the brand ?

For finding the above value we need to add the following values :-

⇒ Ones who said all three .

⇒ Ones who said only brand .

⇒ Ones who said size , brand .

⇒ Ones who said color , brand .

∴ Number of people influenced by brand :-

5 + 8 + 28 + 13

⇒ 26 + 28

⇒ 54

54 were influenced by brand .

How many people were influenced by color or size?

The number of people have to be added :

⇒ Ones who were influenced by color and brand .

⇒ Ones who said color.

⇒ Ones who said color and size .

⇒ Ones who said brand and size .

⇒ Ones who said only size .

⇒ 35 + 13 + 25 + 13 + 8 + 5
