6) A family consists of two grandparents, two parents and three grandchildren. The average age of the grandparents is 67 years, that of the parents is 35 years and that of the grandchildren is 6 years. What is the average age of the family?

A.
 28 4/7
B.
 31 5/7
C.
 32 1 /7years
D. None of these

SOLUTION :

Average age of two grandparents          = 67 years

Then the sum of their ages  =   67 *  2  =  134 years.

Average age of two parents                  =   35  years

Then the  sum of their  ages   =  35 * 2  =   70  years

Average  ages of three grandparents     =   6  years

Then the sum of their ages  =  6 * 3     =   18  years

Now the average age of the family               =    134 + 70  +  18

————————-

2 + 2 + 3

=     222 / 7             =    31 ( 5 /  7 ) years.
