The present age of a brother is 6 years more than four times the age of his sister. Six years hence, brotherâ€™s age will be four years more than thrice the age of the sister. Find the present age of the brother.
Let the sisterâ€™s present age be â€˜nâ€™ years.
=> brotherâ€™s present age = (4n + 6) years
So, according to the question
(4n + 6 + 6) = 3 (n + 6) + 4
=> 4n + 12 = 3n + 22
=> n = 10
Hence, brotherâ€™s present age = (4n + 6) = 46 years
