Question

by sell a watch for rs 395 a man gain 20% what is the s.p of watch

Answer 1

value of s.p is already given 395 Rs.
if you want to calculate c.p then --
because c.p is 100%
then 20% gain means 120% selling value.
120% = 395 then 100% = (395/120)×100= 329.16Rs

Answer 2

hey mate
here is your answer

formulae

= Cost price= { 100/(100+Gain%)×selling price}

Gain%=20%
Cost Price=?
Selling price=395

CP= 100/100+20×395

CP=100/120×395

CP=5/6×395

CP=1975/6

CP=329.16

hence, Cost Price is 329.16₹
