A ‘table set’ consists of a ‘table’ and a ‘table cloth’. For every ‘table set’, the ratio of price of its ‘table cloth’ to the price of the ‘table’ is same. The ‘table cloths’ of two ‘table sets’ A and B are exchanged. The ratio of the prices of the ‘table set’ A and ‘table set’ B before and after the exchange of the ‘table cloths’ are 5:1 and 4:1 respectively. If the price of ‘table set’ C is 8 times that of ‘table set’ D, then the ratio of the prices of ‘table set’ C and ‘table set’ D when their respective ‘table cloths’ are exchanged is (A ‘table set’ is identified by the ‘table’, and not by the ‘table cloth’)
