It is clear that the optimal debt-equity ratio must be less than 2.67 since at this ratio, the value of the firm is Rs 2,75,000, while at a debt-equity ratio of 1.08 it is Rs,2,88,235. The traditional Approach suggests that:

Beyond this range of acceptable leverage the total market value of securities will decline with further increase in I.
The effect of increase in leverage from zero on cost of capital and valuation of the firm thought to involve three distinct phase.
