AVERAGE AGE OF 6 SONS OF A AFAMILY IS 8 YEARS.AVERAGE AGE OF SONS TOGTHER WITH THEIR PARENTS IS 22 YEARS.IF FATHER IS OLDER THAN MOTHER BY 8 YEARS,THE AGE OF THE MOTHER IS?

• 60 years
  
  Total age of 6 sons=6*8=48 years
  If mother's age=M, So father's age=M+8
  Given Age of (Father+Mother+Son)=22*8=176, So M+8+M+48=176, M=60

• Total age of 6 sons =6*8=48
  Total age including parents=8*22= 176
  So age of parents= 176-48=128
  M+F=128
  But F=M+8
  Therefore, M+M+8=128
  2M=120
  M=60.
  
  Hence age of mother is 60 years
