conditional probability question that I am having trouble with

There are 100 people with a certain disease. Of these, 10 are randomly selected to receive a drug that increases the number cured from 50 to 75 percent. what is the probability that a person received the drug if he is known to be cured?

C is the patient being cured & R is the occurance the patient has recieved the drug.

You need to find where

Now find and you have everything you require.
