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

What per cent of water is used for drinking, cooking and gardening together?

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 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 = `30/150 xx 100`

= `100/5`

= 20%
