1. Here,
For the first statement

we have
Newspaper as preferred method is 10% of total 240 i.e = 24

Internet as preferred method is 35% of total 240 = 84

Therefore total newspaper or internet as preffered method = 24 + 84 =108

Therefore fraction =\(\frac{108}{240}\) = \(\frac{9}{20}\)


2. Here,
For 2nd statement

for the age group 20 to 49

35% preferred internet i.e = 84 people

For the age group 50 and older

11% preferred internet i.e = 33 people

Therefore total people preferred internet = 117 people.

Percentage of the total people surveyed = \(\frac{117}{540} * 100\)= 21.6667 = 21.7%


3. Here
For statement 3

For the age group of 50 and older no. of people preferred internet is = 11% of 300 = 33 people

For the age group of 50 and older no. of people preferred radio is = 15% of 300 = 45 people

Therefore the number of people who indicated the Internet is less than the number of people who indicated radio is = \(\frac{(45- 33)}{45} * 100\)

= 26.667 nearly equals to 27%
