Question 76(ii)

An average Urban Indian uses about 150 L of water everyday.
$\begin{array}{cc}\text{Activity}& \text{Litres per person per day}\\ \text{Drinking}& 3\\ \text{Cooking}& 4\\ \text{Bathing}& 20\\ \text{Sanitation}& 40\\ \text{Washing clothes}& 40\\ \text{Washing utensils}& 20\\ \text{Gardening}& 23\\ \text{Total}& 150\end{array}$
How much less percent of water is used for cooking in comparsion to that used for bathing?

Answer 1

Water used for cooking per day = 4 L
Water used for bathing per day = 20 L
Difference between water used for cooking and bathing = 20 - 4 = 16 L
= 16 L water less used for cooking in comparision of bathing
In percentage $=\frac{16}{150}\times 100=\frac{160}{15}=\frac{32}{3}\%$
