12 व्या पंचवार्षिक योजनेमध्ये (2012-17), नियोजन आयोगाने पायाभूत विकासाठी अंदाजे रु. 45 लक्ष कोटींची गुंतवणुकीची तरतूद केली आहे. या गुंतवणुकीपैकी खाजगी गुंतवणुकीचा वाटा किती आहे ?
(1) कमीत कमी 50%
(2) 60%
(3) कमीत कमी 45%
(4) 75%

The correct answer is Option A (At least 50 percent).

Key Points:
• Core Concept
• The Twelfth Five Year Plan (2012–17) prioritized infrastructure modernization through Public-Private Partnerships (PPP).
• Why Correct
• The Planning Commission projected an infrastructure investment requirement of approximately US 1 trillion (roughly Rs. 45 to 55 lakh crore at then-current prices) during the Twelfth Plan period.
• Of this total projected capital outlay, the official plan strategy stipulated that 'at least 50 percent' (50% or ~48-50%) must come from private sector investment via PPP models.
• Key Details
• In the Eleventh Plan, the realized private sector share was around 37%; the Twelfth Plan sought to scale this up past the 50% threshold.
• Exam Traps
• While 45% or 48% were discussed during early preparatory working group drafts, the final Twelfth Plan document established the benchmark target at 'at least 50 percent'.
• Other Options
• Options 2 (60%), 3 (45%), and 4 (75%) do not match the official Twelfth Plan strategy target.
• Key Takeaway: The Twelfth Plan targeted at least 50% private investment in the Rs. 45 lakh crore projected infrastructure outlay.
