Stepbystepexplanation:

30)To find the number of people who prefer radio 1, we have to find the percent of radio 1 as against 640 people.

Radio 1 has 15percent out of 640 people

15/100×640 = 9600/100 = 96 people

Therefore, 96 people out of 640 people prefer Radio 1

31)To find the number of people who prefer radio 4, we have to find the percent of radio 4 as against 640 people.

20/100 × 640 = 12800/100 = 128 people.

Therefore, 128 people prefer radio 4

32)To do this, we have to find the total number of people who prefer Radio 2 and Radio 3 and subtract them together to be able to find the answer.

Number of people who prefer Radio 2:

30/100 × 640 = 19200/100 = 192 people

Number of people who prefer Radio 3:

10/100 × 640 = 6400/100 = 64 people

People who prefer Radio 2 than Radio 3

192 people - 64 people = 128 people

33)Radio 1 attracts 15 percent of listeners. Radio 3 attracts 10 percent of listeners. Sum that up (15% + 10% = 25%) and you have 25 percent. Radio 5 has 25 percent of listeners. Therefore, radio 5 is the answer
