Let the marked price of both the items be Rs. 100a So, selling price of item 'S' = 100a X 0.82 = Rs. 82a Also, selling price of item 'R' = 100a X 0.9 X 0.8 = Rs. 72a ATQ, (82a - 72a) = 400 Or, 10a = 400 So, 'a' = 40 So, total selling price = Rs. (82a + 72a) = Rs. 154a = Rs. 154 X 40 = Rs. 6160 Therefore, overall profit on selling both items = 6160 - 4000 = Rs. 2160
