Three years ago , the average age of A, B and C was 27 years and that of B and C, 5 years ago was 20 years. A’s present age is :
A) 30 yrs B) 35 yrs C) 40 yrs D)48 yrs

• Sum of the present ages of A, B and C = (27 x 3 + 3 x 3) years = 90 years.
  
  Sum of the present ages of B and C = (20 x 2 + 5 x 2) years = 50 years.
  
  A's present age = (90 - 50) years = 40 years.

• three years ago : ( a+b+c)/3 = 27 is average age .
  but, 5 years ago b=c=20 years
  then , 3 years ago b=c=22 years
  we can write (22+22 +a )/3=27 ,a = 37 years
  now , a's present age 37+3 = 40 years .
