at the end of 1994, rohit was half as old as his grandfather. The sum of the years in which they were born in 3844. How old rohit was at end of 1999?

• let yr of birth of rohit=x and gf =y
  x+y=3844
  as,1994-x=1/2(1994-y)
  solving,x=1946
  so at 1999 rohit's age=1999-1946=53

• we know that at the end of 1994 rohit was half the age of his grandfather
  and the sum of the years in which they were born is 3844
  so we do
  3844-1994=1850
  now
  1994-1850=144
  let age of rohit be x
  so age of grandfather=2x
  so x+2x=144
  x=48
  so year in which gf was born=1994-2(48)=1898
  and for rohit 1994-48=1946
  so if rohit was born in 1946 his age at the end of 1999 will be 53

• let rohit age in 1999 be r
  and gf age is gf(say)
  
  before 4 yrs that is on 1995 (end of 1994)
  rohit age= r-4
  gnd father age= gf-4
  
  now--
  r-4=1/2(gf-4)-----eq 1
  
  now for sum of ages...
  (1999-r)+(1999-gf)=3844-----eq 2
  
  on solving both we get r=53 so ans is 53(approx)

• Let at the end of rohit's age= x years
  Then Rohit's grandfather's age = 2x years
  The year in which rohit was born = x-1994
  The year in which grandfather was born = 2x-1994
  According to question:-
  1994-x+1994-2x=3844
  So 3x=144
  or x=48
  And we assumed rohit's age at the end of 1994 = x= 48 years (As calculated)
  So at the end of 1999 i.e. after 5 years rohit's age = 48+5= 53 years

• IN THE YEAR 1994, R=(1/2)GF ;
  LET THEIR BIRTH YEARS OF ROHIT AND GF BE x & y.
  So,
  
  Rohit age = x-1994
  GF age = y-1994
  
  Given that
  x+y=3884;
  x-1994=(1/2)(y-1994)
  
  solving these two we get the birth years of Rohit and GF as 1946 and 1898.
  
  Rohit age @1999 is => 1999-1946=53.

• Let Rohit's grandfather's age at the end of 1994 year = 2x years
  Then at the end of 1994 rohit's age= x years (half of gf age)
  The year in which rohit was born = x-1994
  The year in which grandfather was born = 2x-1994
  According to question:-
  1994-x+1994-2x=3844
  So 3x=144
  or x=48
  And we assumed rohit's age at the end of 1994 = x= 48 years (As calculated)
  So at the end of 1999 i.e. after 5 years rohit's age = 48+5= 53 years
