The average marks obtained by Mahesh in five subjects is 62 and he obtains 71 marks in the sixth subject. What is the average of the marks secured by Mahesh in all six subjects?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e.63.5.
We know that,
Average = Sum of observations/Number of observations
Now,
The average marks obtained by Mahesh in five subjects = 62
The sum of the marks obtained by Mhesh = 62 × 5 = 310
Now, he has 71 marks in the sixth subject
The total marks obtained by Mahesh in six subjects = 310 + 71 = 381
Hence, the average marks obtained by Mahesh = 381/6 = 63.5
