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

1. 4320000
2. 432000
3. 43200
4. 4320

Correct Option: D

We know that , 1 day = 24 hours = 24 × 60 × 60 seconds
⇒ 300 days = (300 × 24) hours = (300 × 24 × 60 × 60) seconds
∴ Number of drops = 300 × 24 × 60 × 60
∵ 600 drops = 100 ml.

∴ 300 × 24 × 60 × 60 drops =		300 × 24 × 60 × 60		ml.
		6

300 × 24 × 60 × 60 drops = (1200 × 60 × 60) ml.

Required answer =		1200 × 60 × 60		litre.
		1000

Required answer = 4320 litre.
