Right, Agreed with your explanation @Krish.

The question is about *recommended* rate of accumulation of sludge in the septic tank. i.e. between 30 to 70 Lit/person/year.

So, the given answer is correct.

Avg BOD per person per day=0.08kg/day/person.
So, for 1year 0.08 * 365 = 29.2.
Please correct me if it is wrong.

@Pravin.

It is the conversion of cubic meters to liters (1000 /1400).

@shivnandan.

What is (1000÷ 1400) ?

Can you explain it for me.

If one cubic metre is equal to 1000 litres then why 1000/1400?
