    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
