given,
market price(M.P) = ₹ 360
discount ( D) = 10 % of 360
= 10 / 100 × 360
= ₹ 36
price of book after giving discount of 10%
M.P - Discount
= 360 - 36 = ₹ 324 = C . P
profit = 20 % of 324
= 20/ 100 × 324
= 648 / 10 = ₹ 64.8
S.P = C . P + profit
S.P = 324 + 64.8
S .P = ₹ 388.8
hence, S.P = ₹ 388.8 and C.P = ₹ 324
