Question

A person who has a certain amount with him goes to market. He can buy 50 oranges or 40 mangoes. He retain 10% of the amount for taxi fare and buys 20 mangoes and of the balance, he purchases oranges. Number of oranges he can purchase is ?

Answer 1

Given that A person buys 50 oranges or 40 mangoes.

Let the price of one orange be x.

Then the total amount the person has 50x.

if 40 mangoes cost 50x.

Then 1 mango = 50x/40

                         = 1.25x.

Given that 10% of the amount for taxi = 10% of 50x

                                                               = 10/100 * 50x

                                                               = 5x.  

                                                                 

Given that he buys 20 mangoes.

From (1) If the cost of 1 mango = 1.25x.

Then the cost of 20 mangoes = 20 * 1.25x

                                                   = 25x.


Money left with the person = Total Money - Cost of Mangoes

                                              = 50x - 5x - 25x

                                              = 20x.

if one orange cost x.

Then 20 oranges cost 20x.

Therefore the number of oranges he can purchase = 20.


Hope this helps!
