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.

Lets C.P. of 20 articles=100 rupees.
then S.P. of 20 articles = 125 (with 25% profit).
S.P. of 1 article =125/20 = 6.25.
The C.P. and S.P. is equal which is 100. So one can sale 16 articles having the price of 6.25 in 100 rupees.
As following
100/6.25=16.
then S.P. of 20 articles = 125 (with 25% profit).
S.P. of 1 article =125/20 = 6.25.
The C.P. and S.P. is equal which is 100. So one can sale 16 articles having the price of 6.25 in 100 rupees.
As following
100/6.25=16.

@Vatsalya.
If C.P of 20 articles = S.P of 25 articles.
Then there will be a loss, not profit.
If C.P of 20 articles = S.P of 25 articles.
Then there will be a loss, not profit.

Simple alternative.
x * 125/100 = 20,
125x = 2000,
125x/125 =2000/125,
x = 16.
x * 125/100 = 20,
125x = 2000,
125x/125 =2000/125,
x = 16.

CP * 20 articles = SP * x --> (1).
By formula, SP = (100 + profit %) * CP.
=> 125/100 * CP.
substitute in (1),
CP * 20 = 125/100 * CP * x.
x = 2000/125.
x = 16.
By formula, SP = (100 + profit %) * CP.
=> 125/100 * CP.
substitute in (1),
CP * 20 = 125/100 * CP * x.
x = 2000/125.
x = 16.

The question says the purchase price of 20 articles is the same as the selling price of x.
Let's say that 20 articles cost me 100. This means selling price of x to be 100.
We are unaware of the purchase price of x. But the profit is given i.e. 25%.
Now given the options, when I tried the last option (D = 25). I got profit to be 25%.

Let the CP of 1 article = 100.
By formula, SP = (100 + profit %) * CP.
125/100 * 100 = 125.
CP of 20 articles = 2000.
CP of 20 articles= SP of x articles.
2000= 125 *x.
Therefore, X = 16.
By formula, SP = (100 + profit %) * CP.
125/100 * 100 = 125.
CP of 20 articles = 2000.
CP of 20 articles= SP of x articles.
2000= 125 *x.
Therefore, X = 16.
