Explanation

Let Komal's age be 6x and Shyam's age be 5x. Four years hence, (6x+4)/(5x+4) = 11/10. Solving: 60x + 40 = 55x + 44, so 5x = 4, x = 0.8. Shyam's present age is 5x = 5(0.8) = 4.

AI explanation

Let the present ages of Komal and Shyam be 6x and 5x. Four years hence their ages will be 6x + 4 and 5x + 4, giving the equation (6x + 4) divided by (5x + 4) equals 11 divided by 10. Solving yields 60x + 40 = 55x + 44, so x = 0.8, and Shyam's present age is 5 times 0.8, which is 4.
