33. After the expiration date, a vitamin's calcium content decreases. If each tablet initially contains 500 mg of calcium, and 325 mg deteriorates, what is the remaining total amount of calcium per tablet?
Answer: A
The remaining total amount of calcium per tablet is 175 mg.
After the expiration date, if each tablet initially contains 500 mg of calcium and 325 mg deteriorates, the remaining calcium per tablet would be 500 mg - 325 mg, resulting in 175 mg.
A) 175 mg
This option is correct because it accurately reflects the calculation of the remaining calcium after the deterioration. Subtracting the 325 mg that has deteriorated from the original 500 mg gives us 175 mg of calcium remaining.
B) 185 mg
This option is incorrect as it does not reflect the correct calculation. If we subtract the deteriorated amount of 325 mg from 500 mg, the remaining calcium cannot be 185 mg.
C) 135 mg
This option is incorrect because it fails to consider the correct subtraction of the deteriorated calcium content. The remaining amount after subtracting 325 mg from 500 mg is not 135 mg.
D) 200 mg
This option is incorrect as it miscalculates the amount of remaining calcium. The proper subtraction of 325 mg from 500 mg does not yield 200 mg.
Conclusion
The correct answer of 175 mg is definitively right as it accurately calculates the remaining calcium after accounting for the deterioration of 325 mg. All other options fail because they do not result from the correct arithmetic applied to the initial calcium content.
