What grade is 43 out of 100?

To calculate the grade, we need to divide the obtained marks (43) by the total marks (100) and then multiply the result by 100 to express it as a percentage.

Percentage = (Obtained Marks/Total Marks) * 100

= 43/100 * 100 = 43

So, if a person scores 43 out of 100, it would be equivalent to 43%. Assigning a letter grade to this percentage may depend on the grading system used in the specific educational institution or context. Please note that different educational systems may have different grade scales.
