You can put this solution on YOUR website! r, b, d for Ravi, Brother, Dad.
The hard part really is reading and transcribing the description into a system of equations. With the system written, simplify and solve according to the method you want or need or know.

Ravi is 5 years older than his brother.2 years ago , Ravi's age was one third his father's age and 3 years from now , his father's age will be 16 less than 2 times the sum of ravi and his brother's ages.What are their present ages?
From the given information, and with R being Ravi's current age, father's current age is: 3R - 4
Father's age is also: 4R - 17
We can then equate these 2 equations to get: 3R - 4 = 4R - 17
Solve for R, Ravi's current age
Subtract 5 from Ravi's current age to get his brother's current age
Subtract 4 from 3 times Ravi's age to get father's current age
