1950 सालापासून केंद्र सरकारच्या महसूली जमा निधी मध्ये केंद्र सरकारचा कर महसूलाचा हिस्सा

The correct answer is Option D (shows no clear trend).

Key Points:
• Total revenue receipts of the Central Government comprise two principal components: Tax Revenue (gross tax revenue less states' share) and Non-Tax Revenue (interest receipts, dividends and profits from public sector enterprises, fees, and external grants).
• Since 1950–51, the relative proportion of tax revenue within total revenue receipts has witnessed cyclical fluctuations across various decades rather than a continuous or monotonic path.
• During periods of economic expansion and tariff hikes, tax revenues expanded rapidly; however, during phases when non-tax revenues surged (due to PSU disinvestments, higher RBI surplus transfers, spectrum auctions, and commercial receipts), the relative share of tax receipts moderated.
• Consequently, historical public finance data for the post-1950 era does not follow a singular upward or downward slope, but rather fluctuates without a persistent directional trajectory.
• In accordance with standard Indian public finance literature and the official MPSC final answer key, Option 4 (shows no clear trend) is the correct answer.
• Key Takeaway: The share of tax revenue in the Central Government's revenue receipts since 1950 exhibits cyclical fluctuations without a definitive single trend.
