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.

Why we have to assume and take Rs 1 here?
Can you explain in detail? please.

20 CP = x SP.
SP = (20/x) CP,
Profit = 25% = 125/100,
125/100 = 20/x,
x = 16.
SP = (20/x) CP,
Profit = 25% = 125/100,
125/100 = 20/x,
x = 16.

(a-b) /b*100=gain percentage.
a=20 b=x gain %=25.
If we solve we get x=16.
a=20 b=x gain %=25.
If we solve we get x=16.

(c.p-s.p)/s.p * 100 = per
(20-x)/x * 100 = 25.
Solve it and you get x=16.
(20-x)/x * 100 = 25.
Solve it and you get x=16.

Cant we solve using equations?
