Answer:
Atleast 7 cars do not have any option to all.
Step-by-step explanation:
Total Cars T = 30
with CD Players C= 15 with AC A = 8
with Alloy wheels W = 6
with all options CnANW = 3
without any option N = ?
T=C+A+W- (CNA + COW + ANW) +
CNANW + N
=> 30 = 15 + 8 + 6 - (CNA + COW + ANW)
+3+N
=> N = (CNA + COW + ANW) - 2
CNANW = 3
=> Min CnA = Min COW = Min AOW = 3
=> N =(3+3 + 3) - 2
=> N = 7
