The average marks of a student in six subjects was initially 110. After re-evaluation, in one subject the marks obtained was reduced from 148 to 112, while in the rest of the subjects the marks remained unchanged. What is the new average marks?

Show answer & explanation

Correct answer: B

Explanation

The correct answer is option 2 i.e. 104

Let the sum of the marks of the students that remained unchanged be x-

So,

Average = (Sum of the marks of the students/Total number of students)

110=x+1486110=\frac{x+148}{6}

660 = x + 148

x = 660 - 148 

x = 512

Now,

New Average = 512+1126\frac{512+112}{6}

New Average = 6246\frac{624}{6} 

New Average = 104
