Question 76(iii)

An average Urban Indian uses about 150 L of water everyday.
$\begin{array}{cc}\text{Activity}& \text{Litres per person per day}\\ \text{Drinking}& 3\\ \text{Cooking}& 4\\ \text{Bathing}& 20\\ \text{Sanitation}& 40\\ \text{Washing clothes}& 40\\ \text{Washing utensils}& 20\\ \text{Gardening}& 23\\ \text{Total}& 150\end{array}$
What per cent of water is used for drinking, cooking and gardening together?

Answer 1

Water used for drinking per day = 3 L
Water used for cooking per day = 4 L
Water used for gardening per day = 23 L
Water used for drinking, cooking and gardening together = 3 + 4 + 23 = 30 L
In percentage $=\frac{30}{150}\times 100=\frac{100}{5}=20\%$
