If 3x - 2(2x - 5) = 2(x + 3) - 8, then the value of x2 + 6x - 5 is:

A bank has a total money supply demand (Md) defined by the equation Md = 0.25Y + 400 - 50r, where Y is national income and r is the interest rate in percentage points. If national income (Y) = 4000 Crore and money supply (Ms) = 1200 Crore, calculate the equilibrium interest rate r.
