A tap drips at a rate of one drop/second. 600 drops make 100 ml. The number of litres wasted in 300 days are?
Answer & explanation
Correct answer: option 4
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
