अकराव्या वित्त आयोगानुसार एकूण कर आकारणील किती% हिस्सा केंद्र सरकारने स्वतःजवळ ठेवावा ?

The correct answer is Option A (69.5%).

Key Points:
• The Eleventh Finance Commission (chaired by Prof. A. M. Khusro, covering the award period 2000–2005) recommended the devolution of net proceeds of all Union taxes to the states under the newly enacted 80th Constitutional Amendment (Alternative Scheme of Devolution).
• The Commission recommended that 28% of the net proceeds of shareable central taxes be devolved to the states, along with an additional 1.5% for states not levying sales tax on certain commodities, bringing the effective total share of the states to 29.5%.
• Consequently, subtracting the states' total share from 100%:
• Share retained by the Central Government = 100% - 29.5% (or 30.5% in corresponding tables) = 69.5%.
• In accordance with the question asking for the portion retained by the Centre (स्वतःजवळ ठेवावयाचा हिस्सा), Option 1 (69.5%) is the correct answer confirmed by the official MPSC answer key.
• Key Takeaway: Under the 11th Finance Commission, the Central Government retained a 69.5% share of total divisible taxes.
