20. A student had got 76 marks out of 80 in Maths; 71 marks out of 80 in Science and
62 out of 80 in English. However, the class teacher entered 26 marks instead of 62 for English. What will be the error in the percentage of marks?

*EXPLAINATION*
hope you find the explanation to be simple enough and try to solve similar questions (Google percentage questions for practice) to get a better understanding of the concept and boost your confidence.
Percentage = (The value you have/ Total value)*100
Multiplying by 100 is required so as to get the per cent means for every 100
French: Marks obtained = 60 ; Total Marks= 80
Percentage = (60/80)*100 = 75%
Similarly, calculate for English and Mathematics
