E Correct answer
Explanation

Let Kamal's age 6 years ago = 6x, Hasan's = 5x. Present ages: Kamal = 6x + 6, Hasan = 5x + 6. Four years hence: Kamal = 6x + 10, Hasan = 5x + 10. Given ratio (6x + 10)/(5x + 10) = 11/10. Solving: 60x + 100 = 55x + 110, so 5x = 10, x = 2. Kamal's present age = 6(2) + 6 = 18 years. Option E (None of these) is correct since 18 years is not listed in A-D.
