Draw your 3circle Venn diagram. Label the circles D,C,I
DCI = .1
so
DC only = .15 (.25.10)
CI only = .20 (.30.10)
DI only = .25 (.35.10)
D only = .20 (.70  .15  .10  .25)
C only = .00 (.45  .15  .10  .20)
I only = .05 (.60  .25  .10  .20)
Add up all the percentages and it is clear that only 90% of the employees read any papers.
That makes .9*2940 = 2646 readers.
So,
a. D only = .2*2940 = 588
b. C only = 0
c. I only = .05*2940 = 147
d. None = .10*2940 = 294
