Sara was pursuing her graduation. Everyday she saw her mother working tirelessly at home after coming back from her work-place. She decided to start a tiffin service to increase her family income. To begin with she started supplying tiffin only in the neighbourhood. Everyday she detailed out the menu after consulting her mother. For informing the people about her service she designed a beautiful informative pamphlet, got it printed and started distributing it through the daily newspapers. She also appointed two delivery boys to deliver tiffins.

The business was slow to begin with but picked-up well afterwards. She was able to earn a profit of 20% of the revenue in the first month.
