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.

100+25%=125
20. ?.
Cross multiply you will get it as 20*125/100;
= 16.

20cp= xsp ---> (1)
Therefore sp= 20cp/x.
profit%= (profit/cp)100= (sp-cp)100
25=( sp-cp)100
Now substitute the value of sp or cp from (1).
25 = (20cp/x - cp)/cp multiplied by 100,
cp will get cancelled and then solve for x to get 16.
Therefore sp= 20cp/x.
profit%= (profit/cp)100= (sp-cp)100
25=( sp-cp)100
Now substitute the value of sp or cp from (1).
25 = (20cp/x - cp)/cp multiplied by 100,
cp will get cancelled and then solve for x to get 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.

Cp of 20 articles = SP of x article.
It means cp = x , Sp = 20.
By formula profit % = (sp - cp) 100/cp.
Therefore. Profit % = Profit % ( for comparing),
(20- x)100/x = 25,
By solving x = 16.
It means cp = x , Sp = 20.
By formula profit % = (sp - cp) 100/cp.
Therefore. Profit % = Profit % ( for comparing),
(20- x)100/x = 25,
By solving x = 16.

20 * C.P = x * S.P ---> (1)
S,P = 1C.P + 0.25 * C.P
S.P = 1.25CP ---> (2).
From (1)
20 * C.P = x * 1.25 * C.P.
c.p gets cancelled;
20/1.25 = x.
x = 16.
S,P = 1C.P + 0.25 * C.P
S.P = 1.25CP ---> (2).
From (1)
20 * C.P = x * 1.25 * C.P.
c.p gets cancelled;
20/1.25 = x.
x = 16.

[20 Article *(C1)= X article * (C2)] (C1 OR C2 are cost per Aricle).
{i.e C2 is more than C1 and also the number of articles are less than 20}
*************************************************
profit is 25%.
25={(C2 -C1)/C1}*100
C2=4/5C1.
ie: 20 * C1 = X*(4/5)C1.
X = 16.
{i.e C2 is more than C1 and also the number of articles are less than 20}

X = 16.

Guys, it just focus only the equation.
Here;
20.cp= x.sp ----------> (1)
Let assume cp=100
Here given gain%=25
Now the equation of sp is;
Sp=(100+gain%)*cp/100.
=(100+25)*100/100
=125.
From equation (1)
20 * 100 = x.125
X = 2000/125
=16.

20.cp= x.sp ----------> (1)
