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.

It is given that;
20(C.P)=x(S.P).
And we know that,
Profit=(SP-CP) /CP.
Therefore,0.25=(SP-(SP*x/20))/(SP*x/20)).
Solving the equation we have,
x=16.
20(C.P)=x(S.P).
And we know that,
Profit=(SP-CP) /CP.
Therefore,0.25=(SP-(SP*x/20))/(SP*x/20)).
Solving the equation we have,
x=16.

If we have given profit amount and also given a loss amount then how can we calculate the cost price of the product?
Please, anyone, clear my doubt.

Let us assume,
Cost price of 20 articles(cp) = 20 R/s.
Selling price of x articles(sp) = x R/s.
Formula:
(S.P-C.P)/C.P*100=profit;
20-x/x*100 = 25.
Cost price of 20 articles(cp) = 20 R/s.
Selling price of x articles(sp) = x R/s.
Formula:
(S.P-C.P)/C.P*100=profit;
20-x/x*100 = 25.

If I bought 20 article and sell 16 article that means 4 article saved, gain 25% (125=20 equ i and 100= x.....Equ 2 ) req article 16 will get easily.

As per given question.
CP of 20 articles =SP of x articles.
CP/SP=X/20.
here CP=x, SP=20.
GAIN%=(GAIN/CP) 100.
25 =(20-X/X)100.
X=16.
CP of 20 articles =SP of x articles.
CP/SP=X/20.
here CP=x, SP=20.
GAIN%=(GAIN/CP) 100.
25 =(20-X/X)100.
X=16.

Let C.P. of 1 article =1.
C.P. of x articles = x.
S.P. of x articles = 1.25x.
Given S.P. of x articales = C.P. of 20 articles.
1.25x = 20.
x=16.
C.P. of x articles = x.
S.P. of x articles = 1.25x.
Given S.P. of x articales = C.P. of 20 articles.
1.25x = 20.
x=16.

(20) cp=(x) sp ------> 1.
Profit=25%.
Means
sp = 125% of cp.
sp = 125/100*((x*sp)/20) {because 1}.
1= 125*x/100*20.
2000/125 = x.
X = 16.
Profit=25%.
Means
sp = 125% of cp.
sp = 125/100*((x*sp)/20) {because 1}.
1= 125*x/100*20.
2000/125 = x.
X = 16.

20*c.p = x*s.p
Here s.p is 125% of c.p,since there is a profit of 25%.
125% = 5/4,
Therefore,
20*c.p=5/4 (c.p)*x.
c.p get cancelled.
X=16.

@Jaya Darshini.
By default if no such values provided for computation in sense we assume such small value as possible that so we assume 1 here.

@Sanjeet.
"profit on one article= (20/x)-'1'
% profit=((20/x)-'1')*100)/1=25"
Why do we have to subtract 1 in the above two steps?
