Question

An article was sold for ₹420 with a profit of 5% .What was its
cost price?​

Answer 1

$\huge \fbox \purple{❥ Answer}$

Let the cost price be x.

profit%=5%

profit= 5%x

       = 0.5

S.P= Cost Price + Profit

S.P= x + 0.5x

S.P= 1.5x

So, 1.5x=420

     x= 420/1.5

     x= 280 Rs.

Hence the cost price is 280 Rs.
