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

Correct option is D

Solution:

Given:
- 1 drop = 1 second
- 600 drops = 100 ml
- 1 day = $$24 \times 60 \times 60$$​ = 86,400 seconds
- 300 days = $$300 \times$$​ 86,400 seconds

Formula Used:

$$\text{Volume of water wasted} = \frac{\text{Total number of drops in 300 days}}{\text{Drops per 100 ml}} \times 100 \, \text{ml}$$​

Solution Steps:

1. Calculate the total number of drops in 300 days:

Total drops = 300 $$\times$$​ 86,400 = 25,920,000


2. Calculate the total volume of water wasted in millilitres:

$$\text{Volume} = \frac{25,920,000}{600} \times 100 = 4,320,000 \, \text{ml}$$​


3. Convert millilitres to litres:

$$4,320,000 \, \text{ml} = \frac{4,320,000}{1000} = 4,320 \, \text{litres}$$​

Final Answer:

The number of litres wasted in 300 days is 4,320 $$\, \text{litres}$$​ .
