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
