उत्तर

In one hour 1 L water is wasted

So, in 1 day or 24 hours water wasted = 1 L × 24 = 24 L.

  1. In one day 24 L of water is wasted
    So, in one week or 7 days
    = 24 L × 7
    = 168 L.
  2. In one day 24 L of water is wasted
    Therefore, in a month which has 30 days, water wasted
    = 24 L × 30
    = 720 L.
  3. In one month 720 L of water is wasted
    Therefore in one year, which has 12 months of water wasted
    = 720 L × 12
    = 8640 L.
