[amp_mcq option1=”98″ option2=”99″ option3=”97″ option4=”100″ correct=”option1″]<\/p>\n
After removing the highest mark:
\nNumber of remaining students = 39
\nAverage marks of 39 students = 58
\nTotal marks of 39 students = Average $\\times$ Number of students
\nTotal marks (39 students) = $58 \\times 39$.
\n$58 \\times 39 = 58 \\times (40 – 1) = 58 \\times 40 – 58 \\times 1 = 2320 – 58 = 2262$.<\/p>\n
The highest mark is the difference between the total marks of 40 students and the total marks of the remaining 39 students.
\nHighest mark = Total marks (40 students) – Total marks (39 students)
\nHighest mark = $2360 – 2262$
\nHighest mark = 98.
