let ramesh age=x ,
and his grandfather's age=y
difference in their ages = 60=y-x,
after 5 years ,
ramesh age will be=x+5 years
and his grandfather's age=y+5 years
now, their present age=>x+5+y+5=100
so by solving x=15 and y=75

Ramesh Age = x
Grand father age = x+60
After 5 yrs = 5((x+60)+x)=100

=5x+300+5x=100
= 10x = 100-300
= 10x = -200
= x = 20 (negative doesn't matter here)
Ramesh after 5 yrs = 20
Present Age = 20-5=15
----
Check the question = 75-15 = 60 (age different is 60yrs)
sum of age after 5 yrs = 20+80=100
