Solution:Akbar created 66 ranks in his Mansabdari System. The word 'Mansab' means rank or position, and a 'Mansabdar' was an officer who held a rank or position in the Imperial army. Akbar's Mansabdari system was based on the decimal system. Abul Fazl mentions 66 ranks (mansabs), but in practice, only 33 mansabs are mentioned in the Ain-i-Akbari. This suggests that some ranks were not granted, and to simplify the system, some ranks were abolished, which reduced the number of ranks in practice. These mansabs were granted from ten up to twelve thousand.
