The sum of the present ages of two brothers Arjun and Karan is 33 years. Two years ago, the product... (kept linear) Five years from now, Arjun will be twice as old as Karan was 5 years ago. Given Arjun + Karan = 33, find Arjun's present age (in years).

Question

Accepted Answer

17. a + k = 33. a + 5 = 2(k - 5) -> a - 2k = -15. Subtract from a + k = 33: 3k = 48, k = 16... recheck: a+k=33 and a-2k=-15; subtract second from first: 3k=48, k=16, a=17. With a=17: 17+5=22, 2(16-5)=22 yes. So Arjun = 17.
