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.

20C=XS
S/c = 20/x = 5/4.
(Given-25%=+1/4profit=1+4/4=5/4).
5-parts20=5*4 =20 ,then x-4parts = 4 * 4 = 16.
Therefore the answer is 16.
S/c = 20/x = 5/4.
(Given-25%=+1/4profit=1+4/4=5/4).
5-parts20=5*4 =20 ,then x-4parts = 4 * 4 = 16.
Therefore the answer is 16.

Cp of 20 articles = sp of x article.
Cp of 1 artical = sp of x/20 article,
25% frofit.
Cp 1 article is = x/20+25%of x/20.
1= 5x/80.
X=16.
Cp of 1 artical = sp of x/20 article,
25% frofit.
Cp 1 article is = x/20+25%of x/20.
1= 5x/80.
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.

Simply using the formula:
SP = 100 + profit × CP/100.
CP : SP.
X: 20.
Simply putting the value you will get the 16 as answer.
SP = 100 + profit × CP/100.
CP : SP.
X: 20.
Simply putting the value you will get the 16 as answer.

X.SP=20CP.
SP/CP=20/x.
SUPPOSE;
SP=20.
CP=x.
profit=SP-CP=y=20-x.
profit%=y x 100/CP.
25=y x 100/x.
solve it.
then, we get the value of x.
SP/CP=20/x.
SUPPOSE;
SP=20.
CP=x.
profit=SP-CP=y=20-x.
profit%=y x 100/CP.
25=y x 100/x.
solve it.
then, we get the value of x.

Cost p = selling p = 20.
Let cp=100.
Sp=125.
125 -------------> 100
1 -------------> 100/125
20 -------------> 100/125 * 20.
So, X = 16.
Let cp=100.
Sp=125.
125 -------------> 100
1 -------------> 100/125
20 -------------> 100/125 * 20.
So, X = 16.

Let the cost price of one article=Rs 100.
profit=25%,
SP =100+25=125,
NOW;
CP of 20 article =SP of X article.
20 * 100 = 125 * X.
X =16.
profit=25%,
SP =100+25=125,
NOW;
CP of 20 article =SP of X article.
20 * 100 = 125 * X.
X =16.

Let CP = a; SP = b;
Then 20a = bx;
Given profit % = 25;
So, b-a/a = 1/4;
Then 5a = 4b;
Compare this with 20a = bx;
Ans = x = 16;
Then 20a = bx;
Given profit % = 25;
So, b-a/a = 1/4;
Then 5a = 4b;
Compare this with 20a = bx;
Ans = x = 16;

One simple rule in this type of question.
When there is profit 25% it taken as 1.25
So. Equ will be : 20/x=1.25.
X=20/1.25.
X=16.
When there is profit 25% it taken as 1.25
So. Equ will be : 20/x=1.25.
X=20/1.25.
X=16.
