39.

the mp of an article is 25 percent above the sp and cp is 20 percent below the sp find the rate of discount and the profit percent

Answer»

Step-by-step explanation:

Mp = SP + 25%

CP = Sp - 20%

LET the C.P be Re. 1

C.P = S.P - 20/100

Re.1 * 100 = 100sp - 20

Rs. 100 = 100sp - 20

Rs. 100 + 20 = 100sp

100sp = Rs. 120

S.P = Rs.120/100

S.P = Rs. 6/5

S.P = Rs. 1.20

M.P = S.P + 25%

M.P = Rs. 1.20 + 25/100

100M.P = Rs 120 + 25

M.P = 1.45

C.P = Rs. 1

S.P = Rs. 1.20

M.P = Rs. 1.45
