He can purchase 20 oranges.

He bought 20 mangoes.
without keeping money for taxi, he can buy additional 20 mangoes or 25 oranges.

For keeping 10% of total money, he will have to surrender amount equal to 20% of 20 mangoes or 25 oranges.He can use buy 80% of 25 oranges.

so he can buy 25*0.8 = 20 oranges.
