Answer»

Given:C.P= ₹ 550M.P= 20% more than the C.P

M.P= C.P + 20%of C.P

M.P = 550+ (20/100)× 550

M.P = 550 + 110= 660

M.P= ₹ 660

Discount = 20%of M.P

Discount= (20/100)× 660

Discount= 2×66= 132

Discount= ₹132

S.P = M.P - Discount

S.P = 660- 132

S.P = ₹ 528

C.P > S.P

Loss= C.P - S.P

Loss= 550- 528

Loss= ₹ 22

Loss%=( loss/C.P)×100%

Loss% =( 22/550)×100

Loss%= 4%

Hence,the loss is ₹22 & loss% is 4%
