Question

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

How much less per cent of water is used for cooking in comparison to that used for bathing?

Answer 1

On the basis of given details, water used for bathing per day = 20 L

Water used for sanitation = 40 L

Total water used per day = 150 L

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 comparison of bathing

In percentage = `16/150 xx 100`

= `160/15`

= `32/3%`
