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.

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.

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.

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.

Let C.P of 1 article Re. 1.
Than C.P of 20 articles is Rs. 20.
Therefore S.P of x articles is Rs. 20.
S.P of x article is Rs. 20.
S.P of 1 article is Rs. (20/x).
Profit on 1 article is = SP-CP.
= (20/x)-1.
Profit = 25% = ((20/x)-1)*100.
25x = (20-x)*100.
x = 16 answer.
Than C.P of 20 articles is Rs. 20.
Therefore S.P of x articles is Rs. 20.
S.P of x article is Rs. 20.
S.P of 1 article is Rs. (20/x).
Profit on 1 article is = SP-CP.
= (20/x)-1.
Profit = 25% = ((20/x)-1)*100.
25x = (20-x)*100.
x = 16 answer.

Let costing price = 100 Rs;
Profit = 25%.
Then selling price = (100+25) = 125 Rs.
If selling prices 125 then costing price 100 Rs.
If selling price 1 then costing price 100 Rs = (100/125) = 4/5.
If selling price 20 then costing price 100 Rs = (4/5)*20 = 16.
Answer: 16.
Profit = 25%.
Then selling price = (100+25) = 125 Rs.
If selling prices 125 then costing price 100 Rs.
If selling price 1 then costing price 100 Rs = (100/125) = 4/5.
If selling price 20 then costing price 100 Rs = (4/5)*20 = 16.
Answer: 16.

Let us problem given profit percentage 25%.
Cost price of articles = 1 rupee.
Then 20 article cost = 20*1 = 20 rupees.
Selling price = x (says).
Now profit% = (profit *100)/cp.
Profit = cp-sp.
So (20-x), profit% = 25%.
(25*20)/100 = 20-x.
Then x =15 rupees. Why we don't use this method ?

Profit = cp-sp.
So (20-x), profit% = 25%.
(25*20)/100 = 20-x.
Then x =15 rupees. Why we don't use this method ?

25% = 1/4.
Out of 5 articles 4 articles sold and 1 is profit.
What about 20 (4 times of 5)?
5 = 4+1.
4 times so, 20 = 16+4.
