explain (Question: 193596.0 )

loss = 1/9 cp and SP =256
loss = SP - CP so 1/9 CP = 256 - CP
10/9 CP = 256 now = 256*9/10 =230.4

Question:
By Selling an article for Rs. 256 a man loses \(\cfrac{1}{9}\) of his cost price. By selling it for Rs. 288, his gain or loss percent is–
Options:
A) 0%
B) 1%
C) 7%
D) 1.5%
Solution:
Ans: (a) Let the C.P. Rs. x then,

loss = Rs. \(\left ( \cfrac {x}{9} \right )\)

S.P. = \(\left (x- \cfrac {x}{9} \right )\) = Rs. \(\cfrac{8x}{9}\) = 256

x = Rs. 288

C.P. = Rs. 288,   S.P.= 288

gain or loss% = 0%

Dear Student,
You are simplifying wrong.
See:
Loss = SP - CP
256 = 1/9x-x
so, x=-288
