A fruit seller has a crate of apples containing 2 bruised apple for every 40 apples in the crate. If 3 out of every 5 bruised apples are not considered suitable for sale and there are 9 apples that aren't fit to be sold in the crate, then how many apples are there in total?
A crate contains 20 oranges and 50 apples and another crate contains 30 oranges and 100 grapes. A worker combines the two crates such that all the fruits are in the same crate. What is the percentage of oranges in the combined crate?
