An average urban Indian uses about $150$ litres of water every day.

Activity	Litres per person per day
Drinking	$3$
Cooking	$4$
Bathing	$20$
Sanitation	$40$
Washing clothes	$40$
Washing utensils	$20$
Gardening	$23$
Total	$150$

What percent of water is used for bathing and sanitation together per day?

Answer 1

The given data shows the distribution of the $150$ litres of water that an urban Indian uses every day.

To find out,

The percent of water used for bathing and sanitation together.

From the given data, we can see that,

Total water used per day $=150$ litres

Water used for bathing $=20$ litres

And water used for sanitation $=40$ litres

Hence, total water used for bathing and sanitation $=40+20$

$=60$ litres

Hence, percent of water used for bathing and sanitation $=\frac{60}{150}\times 100$

$=\frac{2}{5}\times 100$

$=40\%$

Hence, $40\%$ of water is used for bathing and sanitation together per day.
