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.

CP * 20 = SP * X,
25 % PROFIT MEANS (CP+CP*25/100)=1.25 CP
NOW YOU CAN WRITE SP= 1.25 CP,
CP*20=1.25 CP * X
X=20/1.25
X= 16
25 % PROFIT MEANS (CP+CP*25/100)=1.25 CP
NOW YOU CAN WRITE SP= 1.25 CP,
CP*20=1.25 CP * X
X=20/1.25
X= 16

How we came to an assumption that cost of cost of each article = "RS 1" and cost of X articles is rs "X"

Simply, the solution is;
Take C.P as 100% always.
Now,
100%=x.
Profit is 25% so 100+25.
125%=20,
Solve for x,
Ans is 16.

1 step answer:
(1/(20-x)) *100 = 25%.
Simplify, and gets x=16.
Note: (1/(20-x)) is the fraction in terms of Articles.
(1/(20-x)) *100 = 25%.
Simplify, and gets x=16.

Ok, cool see this guys:
As it was given 20(C.P) = x(S.P)--(1).
And {[(S.P)-(C.P)]/C.P} = 0.25--(2).
Solving, x = 16.
As it was given 20(C.P) = x(S.P)--(1).
And {[(S.P)-(C.P)]/C.P} = 0.25--(2).
Solving, x = 16.

CP*20 = SP*X.
CP/SP = X/20.
100/125 = X/20(profit is 25%, therefore if we take CP as 100% then SP will b 125%).
X = 16.
CP/SP = X/20.
100/125 = X/20(profit is 25%, therefore if we take CP as 100% then SP will b 125%).
X = 16.

I think answer is incorrect because it said the CP of 20 articles = SP.
S.P = x.
Then CP will be of 20 article = 20x.
S.P = x.
Then CP will be of 20 article = 20x.

Let assume cp = 100,
Profit is 25%.
sp = 125.
cp 20 = spx,
sp/cp = 20/x,
125/100 = 20/x.
So, the final answer is 16.
Profit is 25%.
sp = 125.
cp 20 = spx,
sp/cp = 20/x,
125/100 = 20/x.
So, the final answer is 16.

Answer is 15 coming.
If we go with options. A) 15.
Profit% = (25-15)/20*100 = 25% profit.
Then answer is 15 right.

25 % profit means 1/4.
20 cp = xsp.
sp/cp = 20/x.
So by formula;
1/4 = sp/cp - cp/cp.
5/4 = 20/x.
5x = 80.
x = 16.
20 cp = xsp.
sp/cp = 20/x.
So by formula;
1/4 = sp/cp - cp/cp.
5/4 = 20/x.
5x = 80.
x = 16.
