Sol.:
p%=5%
sp=250
cp be x.
Now,
p%=(sp-cp)/cp×100%
or 5/100=(250-x)/x
or x/20+x=250
or 21x=20×250
or x=5000/21
:. x= 238.1

Lokendrakumargupta:
your answer is wrong if 5000/21 then answer will be 238.095
We never write exact value,if you round-off 238.095,then it will be 238.1
remember never to write more than 2 places after a decimal point.
do you write 0.000000001 the same,no we write it as 0.& also 99.9999999999999999....... as not99.999.....

ANSWER =
SP of an article = 250
profit = 5%
CP of an article = ?
CP = SP× 100/100+P%
CP = 250×100/100+5
CP = 25000/105
CP = 5000/21
CP = 238.095
Therefore cp for an article is 238.095
