The person can buy 50 oranges or 40 mangoes.
Let the price of one orange be Rs. x.
Total amount the person has = 50 × x = Rs. 50x
Cost of 40 mangoes = 50x So, cost of one mango = 50x/40 = Rs. 1.25x
Amount retained for taxi fare = 10% of 50x = Rs. 5x
20 mangoes bought for 20 × 1.25x = Rs. 25x
Money left with the person = 50 x - (Taxi fare) - (Cost of 20 Mangoes) = 50x - 5x - 25x = Rs. 20x
One orange costs Rs. x.
Therefore, 20 oranges can be bought with Rs. 20x.
Thus, the person purchased 20 oranges.
Hence, option (d) is correct.

Calculation:
The person can buy 50 oranges or 40 mangoes with the amount he has. Let's denote the cost of each orange as O and the cost of each mango as M.
Let the total amount be x.
According to the given information,
50O = x
40M = x
He retains 10% of the amount for taxi fares, so he spends 0.1x on taxi fares.
He buys 20 mangoes with the remaining amount, which is 0.9x.
Now, we can set up the following equations:
40M = 0.9x
20M = 0.45x
0.45x = 0.9x
x = 20M

Number of Oranges purchased:
He purchases oranges with the remaining amount after deducting taxi fares and buying mangoes, which is 0.45x.
From the equation 50O = x,
Number of oranges purchased = 50 * 0.45 = 22.5
Since he can't purchase a fraction of an orange, he can buy 20 oranges with the remaining amount.
Therefore, the number of oranges he purchased is 20 (Option D).
