Comment on Introduction to Percent

Great shortcuts - I would of never thought of those tricks and tips.

Hi Brent,

Question link: https://gmatclub.com/forum/there-are-100-apples-in-a-bag-of-which-98-are...

"There are 100 apples in a bag of which 98% are green and the rest red. How many green apples do you need to remove so that only 96% of the apples are green?"

----------------------
START
We start with 98 green apples and 2 red apples (TOTAL = 100).
98/100 = 98%.
So, 96% of the apples are green.
-----------------------
REMOVE APPLES PHASE
Once we remove 50 green apples, we are left with:
48 green apples and 2 red apples (TOTAL = 50)
So, 48 of the 50 apples are green.
48/50 = 96/100 = 96%.
So, 96% of the apples are green.
-----------------------
Does that help?

Cheers,
Brent
