Answer:

Atleast 7 Cars do not have any option to all

Step-by-step explanation:

Answer 2

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

Atleast 7 cars do not have any option to all..
