Read the following text carefully :
Raghav loved baking and started a small café in his neighbourhood. He personally managed the menu, finances and customer orders. Word spread quickly and soon the café became a popular weekend spot. However, as the number of customers grew, Raghav found it difficult to handle supplies, accounts and marketing alone. He was also facing shortage of capital to meet customers' demands.
He discussed the matter with his friend, Vikas, who said that in today's era of specialization, expansion and diversification, it is not possible for a person to handle everything alone.
Vikas suggested that his sister, Mira, who was a chartered accountant with six years experience in hotel management, could join him. Mira would not only contribute capital but also her valuable experience to the business and help in expanding the café's reach. Raghav agreed and they decided to run the café jointly.
