Profit%=Cost price(C.P)

Cost price(C.P)=?

 

We know that,

P%=  

C.P

S.P−C.P

​

C.P=  

C.P

144−C.P

​  

×100

C.P

=14400−100C.P

C.P  

2

+100C.P−14400=0

C.P  

2

+180C.P−80C.P−14400=0

C.P(C.P.+180)−80(C.P+180)=0

(C.P+180)(C.P−80)=0

C.P cannot be negative.

So,

C.P=80

Hence,the cost price of article is Rs 80.
