First we convert the currency of Kya Kya into Rs. by multiplying the values to 11 and we can get the following table:

In SIFY, profit made by him= $$\ \frac{\ 232-231}{231}\cdot100\%=0.43\%$$

In INFY, profit made= $$\ \frac{\ 105-104.5}{104.5}\cdot100\%=0.47\%$$

In WIPRO, profit made= $$\ \frac{\ 60.5-60}{60}\cdot100\%=0.83\%$$

In TCS, Profit made= $$\ \frac{\ 450-445.5}{445.5}\cdot100\%=1.01\%$$
