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?

The average marks of a student in six subjects was initially 110.

total marks of a student in six subjects initially = $$110\times6$$

= 660
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.

After re-evaluation total marks of a student in six subjects = 660+(112-148)

= 660-36

= 624

New average marks = $$\frac{624}{6}$$

= 104
