Let us assume that he has Rs. 100.
In this he can buy 50 oranges or 40 mangoes.
In other words, the price of an orange is Rs. 2 and that of a mango is Rs. 2.50.
Now if he decides to keep 10% of his money for taxi fares, he would be left with Rs. 90.
Now if he buys 20 mangoes, he would spend Rs. 50 and will be left with Rs. 40, in which he can buy 20 oranges.

Question Analysis:
- The person has a certain amount with him and wants to buy oranges and mangoes.
- He can buy 50 oranges or 40 mangoes with the entire amount.
- He retains 10% of the amount for taxi fares.
- He buys 20 mangoes from the remaining balance.
- The question asks how many oranges he can purchase with the remaining balance.
Solution:
To find the number of oranges he can purchase, we need to follow these steps:
Step 1: Calculate the amount of money spent on taxi fares.
- The person retains 10% of the amount for taxi fares.
- Let's assume the amount of money the person has is 'x'.
- The amount spent on taxi fares will be 10% of 'x'.
- Mathematically, the amount spent on taxi fares = (10/100) * x.
Step 2: Calculate the remaining balance after spending on taxi fares.
- The remaining balance will be the total amount minus the amount spent on taxi fares.
- Mathematically, the remaining balance = x - (10/100) * x.
Step 3: Calculate the amount spent on buying mangoes.
- The person buys 20 mangoes from the remaining balance.
- The cost of each mango is the remaining balance divided by the number of mangoes.
- Mathematically, the cost of each mango = remaining balance / 20.
Step 4: Calculate the remaining balance after buying mangoes.
- The remaining balance will be the remaining balance minus the amount spent on buying mangoes.
- Mathematically, the remaining balance = remaining balance - (cost of each mango * 20).
Step 5: Calculate the number of oranges that can be purchased with the remaining balance.
- The person uses the remaining balance to buy oranges.
- The cost of each orange is the remaining balance divided by the number of oranges.
- Mathematically, the cost of each orange = remaining balance / number of oranges.
Step 6: Substitute the values and calculate the number of oranges.
- The question asks for the number of oranges he can purchase, so we need to find the value of 'number of oranges'.
- Substitute the values we calculated into the equation: cost of each orange = remaining balance / number of oranges.
- Solve for 'number of oranges'.
Answer:
The correct option is (d) 20.
