Final answer:
There are 60 red apples and 120 green apples in the grocery store, with 12 red apples bruised and 30 green apples bruised. This leads to 48 non-bruised red apples and 90 non-bruised green apples.
Step-by-step explanation:
To solve the questions related to the apples in the grocery store, let's perform some calculations step by step.
Number of Red and Green Apples
It is given that exactly 1/3 of the apples are red. So to find the number of red apples:
Total number of apples = 180.
Number of red apples = (1/3) × 180 = 60 apples.
Since the rest of the apples are green, number of green apples = Total apples - Red apples = 180 - 60 = 120 apples.
Bruised Red and Green Apples
Now let's calculate the number of bruised apples:
Number of bruised red apples = (1/5) × 60 = 12 apples.
Number of bruised green apples = (1/4) × 120 = 30 apples.
Non-Bruised Red and Green Apples
Finally, let's calculate the number of non-bruised apples:
Number of non-bruised red apples = Total red apples - Bruised red apples = 60 - 12 = 48 apples.
Number of non-bruised green apples = Total green apples - Bruised green apples = 120 - 30 = 90 apples.
