At the end of 1994 Rohit was 1/4th as old as his grandmother.The sum of the years in which they born is 3843. How old Rohit was at the end of 2011?

• let grandmother age is x yr. at the end of 1994.
  rohit's age will be x/4
  
  born year of grandmother =1994-x
  and born year of rohit =1994-x/4
  
  sum of born year=1994-x+1994-x/4=3843
  x=116
  x/4=29
  at the end of 2011
  rohit's age will be 29+17=46 years.

• ans is 46
  let rohit was born in the year x
  then his age at the end of 1994 is (1994-x)
  given that sum of years born by rohit and grandmother is 3843
  then grandmother was born in (3843-x)
  grandmother age at the end of 1994 is 1994-(3843-x)
  given that at the end of 1994 rohit was 1/4th as old as his grandmother
  i.e 4(1994-x)=1994-(3843-x)
  on ssolving we get x=1965
  age at end of 2011 =2011-1965=46

• let grandmothr b x in 1994
  rohit in 1994=x/4
  1994-x+1991-x/4=3843
  x=116
  rohit=x/4=29 in 1994
  rohit=46 in 2011
  ans. 46

• 1994-R(rohit age)+1994-Gm(grandmother age)=3843
  Therefore, 145=R+gm
  Now R=1/4gm.so 145=5/4gm.
  gm=116,R=29
  R at 2011=29+17=46

• Ans 46
  Rohit =x; Grandm=4x in 1994
  So (1994-x)+(1994-4x)=3843 ie given;
  x=29 ie rohit's age...after 17 yrs ie 2011 rohit=29+17= 46

• let at the end of 1994 grand mother age = x
  so rohit age = x/4
  so the year in which grand mother born= 1994-x
  similarly the year in which rohit was born = 1994-(x/4)
  given
  (1994-x)+(1994-(x/4))=3843
  =>3988-(5x/4)=3843
  =>x=116
  so age of Rohit at the end of 1994= x/4
  =116/4=29
  so 2011-1994 = 17
  so at the end of 2011 Rohit age = 29+17 = 46
