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.

Profit = 25%.
%profit= ((sp-cp) /cp)) * 100.
cp = x.
sp = 20.
25 = (20-x / x)*100.
x = 20 * 4-4x.
3x = 80.
x = 16.
%profit= ((sp-cp) /cp)) * 100.
cp = x.
sp = 20.
25 = (20-x / x)*100.
x = 20 * 4-4x.
3x = 80.
x = 16.

Given:
20cp = x sp.
20cp = 125% cp * x (because profit is 25 %).
20cp = 5/4 cp * x.
20 x 4/5 = x.
16 = cp.
20cp = x sp.
20cp = 125% cp * x (because profit is 25 %).
20cp = 5/4 cp * x.
20 x 4/5 = x.
16 = cp.

CP 20 = SP x.
CP/SP=x/20.
=>CP =x; SP =20.
Profit=20-x (Profit=SP-CP).
25 = ((20-x)/x)*100 (P%=P/CP*100).
CP/SP=x/20.
=>CP =x; SP =20.
Profit=20-x (Profit=SP-CP).
25 = ((20-x)/x)*100 (P%=P/CP*100).

Hello @Dosto
Let me explain,
In this sum we take Easy method:
Cp=(100/100+GAIN%)s.p.
so
x=(100/125)20
x=16.

Let C.P of 20 articles = X.
Let S.P be X+20.
By profit% formulae,
125=X+20/X mul by 100.
The answer is 16.
Let S.P be X+20.
By profit% formulae,
125=X+20/X mul by 100.
The answer is 16.

Hello friends.
We can use given below method or not ?
125/100*x = 20.
=> x = 20*100/125.
=> x = 16.
We can use given below method or not ?
125/100*x = 20.
=> x = 20*100/125.
=> x = 16.

Please explain me how come we assume that the CP of 1 article is Rs. 1. Why can't we assume some other value?

Sp contains cp and profit[25%].
=>x+x/4[25% of x] = 20.
x+x/4 = 20.
=> 5x/4 = 20.
5x = 80.
x = 16.
=>x+x/4[25% of x] = 20.
x+x/4 = 20.
=> 5x/4 = 20.
5x = 80.
x = 16.
