After completing his studies Manav started his own business. He invested ₹2,00,000 as capital which was given to him by his father. He obtained a loan of ₹1,00,000 from his elder brother Ravi, who was working as an assistant manager in Bank of Baroda. In the first year he incurred a loss of ₹50,000 and had to pay to his suppliers their outstanding bills. This created a financial problem for him and he had to take a loan of ₹1,00,000 from the Bank of Baroda on the personal guarantee of his brother. He started doing hard work, lowered the prices and informed his customers about the qualities of goods sold by him. Because of this the sales increased four times and he earned a net profit of ₹75,000 in the second year. His two friends Aman and Suresh showed interest in joining his business. They signed a partnership deed where they decided to share profits equally. Aman and Suresh invested ₹3,00,00 each but Suresh said that he will not take active part in working of the business because of his job.
