If an average Homo sapiens produces 325 g of feces per day, and 30% of it consists of bacteria, how many grams of bacteria does a person's feces consist of per day?

A. 30 g
B. 97.5 g
C. 97.5 g
D. 292.5 g

Answer :

To calculate the amount of bacteria in a person's feces per day, multiply the total daily fecal output (325 g) by the percentage of feces that is bacteria (30%), resulting in 97.5 g of bacteria per day.Thus option b is correct.

If an average homo sapiens produces 325 g of feces per day, and 30% of it consists of bacteria, to find out how many grams of bacteria a person's feces consist of per day, we can perform the following calculation:

Grams of bacteria in feces per day = Total weight of feces per day (in grams) imes Percentage of feces that is bacteria (as a decimal)

Grams of bacteria in feces per day = 325 g imes 0.30

Grams of bacteria in feces per day = 97.5 g

Therefore, the correct answer is (b) 97.5 g.
