Question

At the end of 1994 rohit was half as old as his grandmother. the sum of the years in which they were born is 3844. how old rohit was at the end of 1999?

Answer 1

let the age of rohit at the end of 1994 be x
then the age of his grandmother at the end of 1994 will be 2x
Now,the year in which rohit was born is 1994-x
And the year in which his grandmother was born is 1994-2x
According to question,
1994-x+1994-2x=3844
Solving,3x=1994+1994-3844
3x=144
x=48
At the end of 1999 rohit was
48+5=53 years old
