Hi,

It’s a pretty straight forward question.

Given,

Oranges are bought at the rate of 10 for $25.

So cost of each orange is 25/10.

Also given,

Sold at the rate of 9 for $25.

So, selling price of each orange is 25/9

Question: Profit percentage?

Profit% = (Selling price – Cost price)/Cost price * 100

= {{(25/9) – (25/10)} / (25/10)} * 100

Solving this we get,

= 100/9

= 11(1/9)%

So the answer is D.

Hope this helps.


Regards,
Junaid.

Method 1:

Buying cost of 90 orange=225
selling price of 90 orange=250

\(profit =\frac{25}{225}\)
=11.11%



Method 2:
You invested $25 to get 10 orange and you got your money ($25) back after selling 9 orange.
you left with 1 orange
profit= How much money you get on invested sum/ invested sum
you got 1 orange as profit(that you can sell for $25/9)
\(profit= \frac{25/9}{25}\)
\(Profit=\frac{1}{9}\)
=11.11%

Oranges are bought at the rate of 10 for $25 and sold at the rate of 9 for $25. The profit is:


A. \(2 \frac{1}{2}\)%

B. \(9 \frac{1}{11}\)%

C. \(10\)%

D. \(11 \frac{1}{9}\)%

E. \(12 \frac{1}{2}\)%


Price of 1 orange : 25/10= 2.5$ and SP 25/9
so the profit % : (25/9-25/10)/ 25/10 = option D 11.11%
