Question 868910
A trader sold an article at a profit of 18%. Had it been sold for Rs.222 more, he would have got a profit of 22%. What is the  cost price .
Let cp of article is Rs X 
sp of article after earning profit of 18% = 1.81 X
if sp is 222 more than 1.18x than profit will  be 22%
new sp will be  1.18X+222 (1)
it will earn 22% means new sp would be 1.22 X (2)
as  per given conditions  equation (1) will be equal to equation (2)
1.22 x =1.18 x +222
1.22 X -1.18 x =222
0.04 X= 222
X = 222/.04  = 22200/4
X= RS 5550
