Practicing Success
A tap drips at a rate of one drop/second. 600 drops make 100 ml. The number of litres wasted in 300 days are? |
4320000 432000 4320 432 |
432 |
1 sec → 1 drop in 30 days no. of seconds = ( 24 × 60 × 60 × 30) No. of ml wasted = \(\frac{100 × 24 × 60 × 60 × 30 }{600}\) = 4320 × 100 = \(\frac{432000}{1000}\) = 432 |
