A teacher calculated the mean of 27 students mark to be 62. A student who later completed the assessment got a mark of 53. What is the new mean of the class, to two decimal places?

first of all the average score of students is 62.

and there are 27 students

so full marks scored by students are 27×62= 1674

and 1 new students added to that so his score would be 1674+ 53(his marks)= 1727

so now the mean of students are beause there are one more students so 27+1 = 28 then 28÷1727= 61.6 is the mean now
