# How many oranges bought for 100$

A fruit merchant sells 20 oranges for 10$ thereby making profit of 25%.

How many oranges did he buy for 100$?

**Answer**– 250 Oranges

20 oranges for 10$ => selling price per orange = 0.5 $

Since this sale is at 25% profit, it means that the purchase price per orange was 0.4 $, which, in turn, implies that he *could have* bought 250 oranges for 100$. Whether he actually ‘*did buy*‘ that many is a different matter. 🙂

** Answer**– 266.67 Oranges

20 oranges for 10$ => selling price per orange = 0.5 $

Since this sale is at 25% profit, it means that the purchase price per orange was 0.375 $,

0.5$ = 100%

? = 25%

(25/100)*0.5 = 0.125$ (Profit per Orange)

0.5- 0.125 = 0.375$ (Original Cost per Orange)

So for 0.375$ we can get 1 orange. For 100$ we can get 266.67 oranges.

(100/0.375)*1 = 266.67

number of oranges has to be a natural number, but not fraction.

20 oranges for 10$ implies 1 orange for 0.5$ and also 200 oranges for 100$.

If he had bought 25 oranges for 10$, he makes 25% profit by selling 2o oranges for 10$.

So for 100$, he would have bought 250 oranges.

merchent gets 1 orange for = (10/20)*(100/125) $

= 0.4 $

for 100$ merchent gets = 100/0.4

= 250
