B Correct answer
Explanation

S + N = 36. Four years ago: (S-4) = 3(N-4). S-4 = 3N-12 => S = 3N-8. Substitute: 3N-8 + N = 36 => 4N = 44 => N = 11. Naveen's age after 5 years = 11 + 5 = 16.

AI explanation

Let Sandeep's present age be S and Naveen's present age be N, so S + N = 36. Four years ago, their ages were S - 4 and N - 4, leading to the equation S - 4 = 3(N - 4), which expands to S = 3N - 8. Substituting this into the first equation gives 3N - 8 + N = 36, so N = 11. After 5 years, Naveen's age will be 11 + 5 = 16 years.
