Reverse DCF

(a) A consumer company has last-year FCFF ₹900 cr; market EV is ₹45,000 cr; WACC 11.5%; terminal growth 5%; 10-year explicit stage. Set up the equation for implied growth, state why it has a unique root, and solve it numerically (bisection or reverse_dcf). Repeat for WACC of 10.5% and 12.5%. (b) For a value-driver model with $V$ = ₹20,000 cr, $\text{NOPAT}_1$ = ₹1,000 cr, RONIC 25%, WACC 11%, find the implied perpetual growth in closed form.
