One of the classical examples of competitive market structure in Pakistan is telecommunication sector. The major cellular companies in this sector are Mobilink, Ufone, Telenor, Warid and Zong. Among these companies, Mobilink, a subsidiary of the Orascom Telecom Holding, is Pakistan's leading cellular and Blackberry service provider. It has more than 30 million subscribers. The company has almost 15,000 employees and is paying 4 million rupees to these employees. Suppose the company has taken a loan of 100 million rupees from SummitBank and is paying 3.5 million rupees as interest payments. The total rent of various franchises is 50 million rupees. According to "Customer's Perception Survey" conducted by Pakistan Telecom Authority (PTA) in 2011, the company had been ranked as "excellent" among all cellularservice providers in the country. This survey showed an increased demand of Jazz SIMs in the country. The demand and supply function of Jazz SIM is as follows:
Qs= - 80+ 8P
Qd= 70 - 2P
