Question

A shop keeper marks his goods at 30 percent above the Costprice and then gives a Dicount of 10 percent. find his gain percent

Answer 1

Answer:

here is your answer

Step-by-step explanation:

M.P is 30 percent above C.P

let C.P be x

then M.P = x + 30% × x

M.P = x + 30/100 × x

LCM= 100

M.P = 130x/100

S.P= (100-d/100 )×M.P

90/100 × 130x/100= 117x/100 => 1.17x

P= S.P - C.P = 1.17x - x => 0.17x (we take x as 1 in algebra).

P% = P/C.P × 100 => 0.17x/x × 100= 17% (x and x cancels. 0.17 × 100 = 17)
