b) Prepare a limited entry decision table for the following case:
A wholesaler has three commodities to sell and has three types of customers. Discount is given as per the following procedure:
i) For DGS & D orders, 10% discount is given irrespective of the value of the order.
ii) For orders more than Rs. 50,000/- agent gets a discount of 15% and the retailer gets a discount of 10%.
iii) For orders of Rs. 20,000/- or more upto Rs. 50,000/- agent gets a discount of 12% and the retailer gets a discount of 8%.
iv) For orders of the value less than Rs. 20,000 agent gets 8% and retailer gets 5% discount.
The above rules do not apply to the furniture items where in a flat rate of 10% discount is admissible to all customers irrespective of the value of the order.
