Answer:
(A) 40%
(B) 60%
Step-by-step explanation:
Given:
Total number of cars = 200
Cars in parking lot on Friday = 120
Total number of cars = Total cars on Friday + Total cars on Saturday.
⇒ 200 = 120 + Total cars on Saturday.
⇒ Total cars on Saturday = 200 - 120 = 80
So, 80 cars were in parking lot on Saturday.
(A)
Percentage of cars in parking lot on Friday is given as:
Therefore, 60% of the cars were in the parking lot on Friday.
(B)
Now, since 60% of the cars were parked on Friday, the remaining percent will be on Saturday.
Therefore, percentage of cars in parking lot on Saturday = 100% - 60% = 40%. This can be verified with the same formula used in part (A).
