A grapefruit is 8% heavier than an orange, and an apple is 10% lighter than the orange.
By what percentage is the grapefruit heavier than the apple?
THANK YOU!!

Hence, the grapefruit is 20% heavier than the apple.

Step-by-step explanation:

Let the weight of orange be x.

This means that the weight of grapefruit is:

       1.08x

( Since grapefruit is: 8% heavier than orange )

Also, the weight of apple is 10% lighter than apple.

This means that the weight of apple is: 0.90 x

Hence, the percent change in the weight of grapefruit as compared to apple is calculated by:

1/5^2 = 7.56/45
