A man gains much by selling a watch for Rs.1500as he loses by selling it for Rs.1200. Find the cost price of the watch.

Let the CP be x.

if SP is 1500 then gain=1500-x.

if SP is 1200 then loss=x-1200

according to the question,

1500-x=x-1200

1500+1200=x+x

2x=2700

x=2700/2=1350

so CP is 1350 Rs.
