Disparity Sudoku (Daily Sudoku League #103)

Disparity Sudoku along with Black and White Killer Sudoku appeared in the Sudoku Surprise test which was held in November 2014 on the Logic Masters India website. As this Sudoku type was completely new to me, I created this Sudoku to prepare for this test and to understand Disparity Sudoku better.

This Disparity Sudoku is my 103rd contribution to The League of Extraordinary Ladies and Gentlemen. Can you solve this Disparity Sudoku puzzle?

Rules of Disparity Sudoku
