The following table gives the marks obtained by six students in six different subjects in an examination.
The maximum marks for each subject are given in the brackets.
Question 71
What is the average of total marks obtained by Aman, Kartik, Mukesh and Lokesh in all subjects?
Solution
Total marks obtained by Aman in all subjects: 95+65+115+100+125+90 = 590
Total marks obtained by Kartik in all subjects: 60+95+130+95+100+80 = 560
Total marks obtained by Mukesh in all subjects: 105+90+95+110+140+85 = 625
Total marks obtained by Lokesh in all subjects: 55+115+60+65+75+70 = 440
The average of these total marks would then be $$\frac{590+560+625+440}{4}=\frac{2215}{4}=553.75$$
Therefore, Option D is the correct answer.Â
