Marks: +1, -0

A tap drips at a rate of one drop/sec. 600 drops make 100ml. The number of litres wasted in 300 days is

4320000
432000
43200
4320

Solution:

300 days = (300 × 24) hours = (300 × 24 × 60 × 60) seconds
∴ Number of drops
= 300 × 24 × 60 × 60
Since 600 drops = 100 ml.
∴ 300 × 24 × 60 × 60 drops
=

({300×24×60×60}/6)

ml.
= (1200 × 60 × 60) ml.
=

({1200×60×60}/{1000})

litre
= 4320 litre.
