Mathematics · Viability Gap Funding and Project Finance

A state government proposes a 'Drinking Water and Sanitation' project under the Public-Private Partnership (PPP) model. The Total Project Cost (TPC) is estimated at ₹1,000 crore. The project is eligible for Viability Gap Funding (VGF) under Sub-scheme 2 (Social Infrastructure), where the Central Government provides up to 30% VGF and the State Government provides an additional VGF of up to 30% of TPC (Total VGF = 60%). If the private developer's equity contribution is 15% of the TPC, calculate the amount of Debt the developer needs to raise from the banking system after considering the maximum total VGF support.
