Question

Raksha is 25 years ypunger than her father . After 10 year their ages will be in ratio of the 1:2 find their present ages

Answer 1

At present-

        let age of Raksha be x , so age of father will be x+25

After 10 years-

       age of Raksha will be x+10 and age of father will be (x+25)+10

Now solve the ratio as :

        (x+10)/(x+25+10) = 1/2    ,    you will get x is 15.
