Vedclass · Answer

(A) For the healthy growth of fish,the concentration of dissolved oxygen $(DO)$ in water should be more than $6 \ ppm$. If the concentration of dissolved oxygen is less than $6 \ ppm$,the growth of fish is inhibited. Biochemical Oxygen Demand $(BOD)$ is the amount of oxygen required by bacteria to break down the organic matter present in a certain volume of a sample of water. Clean water would have a $BOD$ value of less than $5 \ ppm$. Therefore,$X = 6$ and $Y = 5$.

The concentration of dissolved oxygen in water for the growth of fish should be more than $X \ ppm$ and the Biochemical Oxygen Demand $(BOD)$ in clean water should be less than $Y \ ppm$. $X$ and $Y$ in $ppm$ are,respectively:
