Question

lily brought a bicycle coasting R 18,000 After some modification of 22,000. Find the profit / loss percentage​

Answer 1

Let the C.P. of the 1st bicycle= Rs. x. 

Then, C.P. of the 2nd bicycle = Rs. (18000−x)

S.P. of 1st bicycle = Rs. x×100125= Rs. 45x

S.P. of 2nd bicycle = Rs. (18000−x)×10080 = Rs. 54(18000−x)

Since Mohan neither gains nor loses, his total S.P. = Total C.P.

⇒45x+54(18000−x)=18000

⇒45x−54x=18000−14400=3600

⇒2025x−16x=3600⇒9x=3600×20

⇒x=93600×20=8000

∴ C.P. of 1st bicycle
