Some Math help

Правка en1, от chaiCoder, 2016-02-18 21:46:02

Hi,

New to CF. Hello!

I have some math trouble with the following. Please help me. It seems too simple, but I'm kinda stuck on it for quite sometime now..

Let's say I'm a shopkeeper. I have 1000 apples with me (some are rotten), out of these I sold 700 apples today, meaning I sold 70% of the apples I have. Out of these 700, 210 apples were rotten (gone bad)(which is 30%). I need to know proportionately the number of good apples I had in the beginning (in place of 1000).

Please help. I can't seem to get my head around it.
