The cost price of 20 articles is the same as the selling price of x articles. If the profit is 25%, then the value of x is:
Answer: Option
Explanation:
Let C.P. of each article be Re. 1 C.P. of x articles = Rs. x.
S.P. of x articles = Rs. 20.
Profit = Rs. (20 - x).
 |
 |
20 - x | x 100 = 25 |  |
| x |
2000 - 100x = 25x
125x = 2000
x = 16.

C.P of each article be R.S 1. So 20 article is 20 R.S.
We need to find S.P of x = R.S 20. Profit is 25%.
So 25% of 20 is 5 R.S.
= 25/100*20 = 5.
So S.P is 20+5 = 25.
= 25/20 = 1.25 for 1 article.
= 1.25*16 = 20.
So it is 16.
We need to find S.P of x = R.S 20. Profit is 25%.
So 25% of 20 is 5 R.S.
= 25/100*20 = 5.
So S.P is 20+5 = 25.
= 25/20 = 1.25 for 1 article.
= 1.25*16 = 20.
So it is 16.

Supposed that the price of 20 articles is 100$.
Then the selling price is 100$ + 100$*0.25 = 125$.
Since the cost price is equal to the to sold price of x article.
We get 20 articles can be sold for 125$.
x articles can be sold for 100$.
x = 100$*20/125$.
x = 16 articles.
Then the selling price is 100$ + 100$*0.25 = 125$.
Since the cost price is equal to the to sold price of x article.
We get 20 articles can be sold for 125$.
x articles can be sold for 100$.
x = 100$*20/125$.
x = 16 articles.

Hi guys I can't understand this line:
S.P. of x articles = Rs. 20.
S.P. of x articles = Rs. 20.

I think it should be 25 if C.P is 200 of 20 articles.

Profit on one article = (20/x)-1.
% profit = ((20/x)-1)*100)/1 = 25 how this step is used?
% profit = ((20/x)-1)*100)/1 = 25 how this step is used?

Today I know maths is a tricky game which can be played through own idea.

We have to know about value of x? So there is 20 Articles and profit is 25 so put the formula.
SP = (100+gain /100*CP).
Thus (100+25/100*25).
So now calculate it 125/20000.
16 answer.
If I'm wrong then correct me ?
SP = (100+gain /100*CP).
Thus (100+25/100*25).
So now calculate it 125/20000.
16 answer.

C.P of 20 = S.P of x.
20 C.P = S.P x.
C.P/S.P = x/20.
i.e. C.P = x and S.P = 20.
Gain = S.P-C.P.
= 20-x.
So gain% = (gain/C.P)*100.
= (20-x)/x*100 = 25 (given).
= (2000-100x)/x = 25.
2000 = 125x-100x = 2000 = 25x.
x = 2000/25 = 16.
We can calculate this type of question through this method check.
20 C.P = S.P x.
C.P/S.P = x/20.
i.e. C.P = x and S.P = 20.
Gain = S.P-C.P.
= 20-x.
So gain% = (gain/C.P)*100.
= (20-x)/x*100 = 25 (given).
= (2000-100x)/x = 25.
2000 = 125x-100x = 2000 = 25x.
x = 2000/25 = 16.

The question is not that it is too hard to understand, it is that the question makes no sense in plain English. If you are trying to get someone to figure out what the cost of an article is that costs 20 Rs or $ or any other denomination with a 25% profit, then perhaps you should actually ask that question.
