Stmt 1 tells us that there are 17 directors total at the meeting an none are absent. We don't know how many are directors for each company though.
Setting up the formula for overlapping sets we would have
17 = k + r + 0 - both
Insufficient
Stmt 2:
Tells us how many directors for each company.
Total = 12 + 8 + 0 - both
Two unknowns so we can't solve.
Together:
17 = 12 + 8 + 0 - both
17 = 20 - both
both = 3
Choose C
