A wholesaler has three commodities to sell and has three types of customers. The discount is as per following rules: (i) (ii) (iii) (iv) For Govt. orders, 15% discount is given irrespective of the value of the order. For orders of more than $20,000, an agent gets a discount of 20% and the retailer 15% respectively. For orders of value between $10,000 and $20,000, agent gets discount of 15% and the retailer gets 10%. For order of value less than $10,000 the agent and retailer get discount 10% and 5% respectively. The above rules do not apply to furniture items. However, in case of furniture items, a flat rate of 10% discount is admissible to all type of customers. Prepare a decision table. Ps: be sure to show the Checksum calculations
