George went to a fruit market with certain amount of money

George went to a fruit market with certain amount of money. With this money he can buy either 40 oranges or 40 mangoes. He retains 10% of the money for taxi fare and buys 20 mangoes. How many oranges can he buy?

This problem repeats another one in the library (at most with different numbers), so it's left out of browsing.
