The correct option is 2) 38 years.

The new average age of the group is 38 years.

The average age is of 8 persons = 40 years.

Sum of the ages = 40× 8 = 320

Total sum of 7 persons age = 320 - 60 = 260

As one new person is added in the group,

Hence, the total sum of ages = 260+44 = 304

New average =  304/4 = 38.

The new average age of the group is 38 years.
