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.

Use the formula:
CP = (SP*100)/(100+profit).
CP = (20*100)/(100+25).
CP = 16.
CP = (SP*100)/(100+profit).
CP = (20*100)/(100+25).
CP = 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?

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.
We can calculate this type of question through this method check.
