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 :

97.5g because 30% of 325g, the total fecal matter produced per day, equals 97.5g, representing the amount of bacteria present in a person's feces daily. This calculation demonstrates the proportion of bacteria within the total fecal matter output.Thus option b is correct.

The calculation involves finding 30% of 325g, which equals 97.5g. This means that 97.5 grams of the total fecal matter consist of bacteria per day.

In the given scenario, the total amount of feces produced by an average human per day is 325g. From this, we need to find the portion that consists of bacteria, which is 30% of the total. To calculate this, we multiply 325g by 0.30, resulting in 97.5g.

Therefore, the correct answer is 97.5g, as per the calculation. This quantity represents the amount of bacteria in a person's feces per day, based on the given parameters of fecal production and bacterial composition.

Thus option b is correct.
