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.

Shortcut method:
20 C.P = X S.P.
C.P/S.P = X/20.
Profit 25% --> 125.
So that 125---> 25 means.
100---> ?
Answer = 16.
20 C.P = X S.P.
C.P/S.P = X/20.
Profit 25% --> 125.
So that 125---> 25 means.
100---> ?
Answer = 16.

100*20 = 125*x.
x = 100*20/125.
x = 16.
x = 100*20/125.
x = 16.

This question is quite simple but the language or the way of asking made in inconvenient to solve. Here is another way to ask the same question.
Cost of an article is 1/20. If you sell it at 25% profit then find out the Selling price?

It's VERY EASY!
Let C.P of 1 article is 1Rs. than C.P of 20 articles is 20 RS.
Again S.P of X articles is 20 RS.
So, S.P of 1 article is 20/x.
Now putting the CP and SP of 1 article and profit% in the standard formula given below.
SP = CP*(100 + GAIN)/100.
We have,
20/x =1*(100 + 25)/100.
20/x = 125/100
2000 = 125x.
x = 16.

We have,

20/x = 125/100
2000 = 125x.
x = 16.

Cost price of m article is equal to selling price of n article then,
Gain or loss% = (m - n/n) *100.
Here,
25 = (20 - x/x)/100.
X = 16.
Gain or loss% = (m - n/n) *100.
Here,
25 = (20 - x/x)/100.
X = 16.

Very well explained and thanks a lot.

@Sanjeet could you tell me.
Hence, S. P of x article is Rs. 20.
So S. P. of 1 article = 20/x.
After that, I can't understand why are you using -1 for profit on one article.
Profit on one article= (20/x) - 1.
Please explain me.

Let's assume that the CP of each item is Re 1.
Thus, for 20 items, total CP would be Rs 20.
Given that, he makes a profit of 25%,
ie) He is selling every Re 1 item for Rs. 1.25.
Now, since the CP of 20 items (i.e Rs 20) is equal to the SP of x items, therefore,
x * 1.25 = 20.
=> x= 16.
Thus, for 20 items, total CP would be Rs 20.
Given that, he makes a profit of 25%,
ie) He is selling every Re 1 item for Rs. 1.25.
Now, since the CP of 20 items (i.e Rs 20) is equal to the SP of x items, therefore,
x * 1.25 = 20.
=> x= 16.
