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 |  |

2000 - 100x = 25x

priya...
in general form.
let the cost of 20 article = y rs
so cost of 1 article= y/20rs
and cost of x article = xy/20
so the profit= price-sailing price/sailing rate
25=(y-x*y/20)/(x*y/20)
by solve this u got 16 answer

x=16

@priya :- when u got s.p of x article = Rs. 20 and c.p of 1 article is re.1 so for 'x' article c.p will be Rs. x .
now s.p - c.p = profit
hence 20 - x . = profit .
now s.p - c.p = profit
hence 20 - x . = profit .

Then where is the solution of 25%.
Chinni said:

profit=s.p-c.p
hence cost of 1 article=1
s.p of 1 article=20/x
profit=(20/x)-1
hence cost of 1 article=1
s.p of 1 article=20/x
profit=(20/x)-1
