Answer
View full question & answer→(i) Water used in bathing and sanitation together $=20+40=60$ L per day
$\therefore$ Percentage of water used in bathing and sanitation together per day $=\frac{60}{150} \times 100=40 \%$
(ii) Water used in cooking $=41.$
Water used in bathing $=201.$
So, in comparison to bathing, water used in cooking is less by $(20-4)$ i.e. 161
$\therefore$ Percentage $=\frac{16}{150} \times 100=\frac{32}{3} \%=10 \frac{2}{3} \%$
(iii) Water used in drinking, cooking and gardening together $=(3+4+ 23)\text L= 30\text L$
$\therefore$ Percentage of water used in cooking, drinking and gardening together per day $=\left(\frac{30}{150} \times 100\right)$
$=\left(\frac{3000}{150}\right)=20 \%$
(iv) By 'saving water', we can help the humanity in a better way. We can use that amount of water which $\text s$ necessary for our need and can easily stop the wastage of water.
