Answer 2

Answer:

The number of passengers who like only coffee is greater than the passengers who like only ice cream by 100%

Step-by-step explanation:

Let us take the number of passengers be 100

Let C be the set of passengers who like Coffee

T be the set of passengers who like Tea

I be the set of passengers who like Ice cream

The number of passengers who do not like tea, coffee and ice cream = 5

The number passengers who like tea, coffee and ice cream = 10

The number passengers who like tea, coffee  = 20

The number passengers who like only tea, coffee  = 20 - 10 = 10

The number passengers who like ice cream, coffee  = 25

The number passengers who like only ice cream, coffee  = 25- 10 =  15

The number passengers who like ice cream, tea  = 25

The number passengers who like only ice cream, coffee  = 25- 10 =  15

The number passengers who like coffee = 55

The number passengers who like only coffee = 55 - 10 - 10 - 15 = 20

The number passengers who like tea = 50

The number passengers who like only tea = 50 - 10 - 10 - 15 = 15

The number passengers who like ice cream = 50

The number passengers who like only ice cream = 50 - 10 - 15 - 15 = 10

Since the number of passengers who like only coffee  =20 and the number of passengers who like only ice cream = 10

The number of passengers who like only coffee is greater than the passengers who like only ice cream by 100%
