Let Jalal's salary 2 years ago = J, Millat's salary two years ago = M
Given: J = M/2, Jalal received a raise of 5% each year and Millat received a raise of 10% each year for 2 years.
Current salary of Jalal = J * 1.05 * 1.05 = M/2 * 1.05 * 1.05
Current salary of Millat = M * 1.1 * 1.1
Jalal's current salary as percentage of Millat's current salary = \(\frac{M}{2 * 1.05 * 1.05/M * 1.1 * 1.1 * 100}\) = 45.55% \(\approx\) 46%
So, current answer is option B.
