Answer:
336 version
Step-by-step explanation:
To determine the total possible number of combination we will use the product rule
Total numbers of exterior colour 7
Total number of interior colour 3
Total number of interior style 4
Total number of transmission option 2
Total number of engine option 2 therefore the total combination is
7*3 *4*2*2 = 336 possible combination
9t = 27.99
5t = ?
Cross-multiply : 9t? = 139.95t
?=15.55
5*6=30
and 6*5=30
basically we have to take Lcm of 5 and 6=30
30th day they both will be together
