In the life sciences department, 65% of the total number of students watch the news on

television, 40% read a newspaper and 25% both read a newspaper and watch the news on

television. What percentage of the department's students do not watch the news on

television and do not read a newspaper?

(1) 0%

(2) 10%

(3) 20%

(4) 25%

My solution:

100 students.

40-25 = 15 only newspaper

65- 25 = 40 only TV

answer is 2.. 10%

not sure..

guess:

65+25 = 90?

100-90 is 10?

not sure...

DIGITS question:

(2) 1AB

(3) 11A

(4) 10A

answer 4
