The average age of 8 persons in a committee is increased by 2 years when two men
aged 35 years and 45 years are substituted by two women. Find the average age of
the two women.

• 48 years
  
  Let initial average age of 8 persons was x years, then total age of 8 persons=8x
  Let the average age of two women replacing two men of age 35 & 45 years be y, then
  (8x -35 -45 +2y)/8 =x+2
  => 8x + 2y -80 =8x +16
  => 2y=96 or y=48
