x= 15
Ram's age is 15
and Ram's father age is 45

Answer 2

Let ram's age be x.
so,father's age is 3x.

After five years,
   sum of their ages=70
   Ram's age after 5 years+Father's age after 5 years=70
   (x+5)+(3x+5)=70
   x+3x+5+5=70
   4x+10=70
   4x=70-10
   x=60/4
   x=15 
Ram is 15 years old and his father is 45 years old at present.
