Question

There is a loss of 10% on selling a bicycle for Rs. 360, how much should be sold in that bicycle to make 10% profit?​

Answer 1

it is very easy, dear.

here first we should find the cp. by using formula of sp-l%of cp=cp.

when we find cp=400,

put that on second and find out the new sp that gain 10%.

do as follow .

cp=400

sp=?

profit=10%

now, cp= sp-p% of cp

or, 400= sp-10/100×400

or, 400+40=Sp

therefore = 440.

let's hope you understood .
