Question

robin is 25 years younger than his father.after 10 years,there ages will be in the ratio 1:2.Find their present ages

Answer 1

At present R=F-25 After 10 years 2R=F 2(F-25)=F 2F-50=F So F=50 and R =F/2=50/2=25 So at present:- R means Rohit is of age = 25-10=15yrs His father F is of age =50-10=40 yrs

Answer 2

Age of robin = 25 years
Age of robin after 10 years = 25+10 years
= 35 years
Ratio of age of robin and father =1:2
Meaning father is twice as old as robin that is
Robins father age is 35*2=70
Now let's subtract 10 years to find his present age=70-10=60years


Age of robin=25years
Age of father =60 years

Hope this helps
