The production cost and the cost prices of a cycle at different levels are:

(i) Let us calculate, by selling cycle, how much profit percentage, the retailer has made.
(ii) Let us calculate and observe that by selling cycle, what the profit percentage, the wholesaler has made.
(iii) Let us calculate and write the profit percentage, that the producer has made by selling cycle.
(iv) Let us calculate and write that how much profit percentage has to be given more by a buyer than the production cost to buy a cycle.
(v) If a buyer buys a cycle directly from the producer and the producer has a profit of 30%, then how much money, the buyer will save — let us calculate and write it.
