Answer:
The answer is "5.4% and 15,23,500".
Explanation:
Calculating the capital cost:
[tex]=(1-\frac{1}{1.46})\times 10.91\% \times (1-39\%)+(\frac{1}{1.46})\times 4.84\% \\\\=(\frac{1.46-1}{1.46})\times \frac{10.91}{100} \times (\frac{100-39}{100})+(\frac{1}{1.46})\times \frac{4.84}{100} \\\\ =(\frac{0.46}{1.46})\times \frac{10.91}{100} \times (\frac{61}{100})+(\frac{1}{1.46})\times \frac{4.84}{100} \\\\=\frac{306.1346}{14600}+\frac{4.84}{146} \\\\= 0.021+0.033 \\\\ =0.054\\\\= 5.4\%[/tex]
Maximum amount to be spent
[tex]=\frac{277,000\times 100 }{5.4} \times (1-\frac{1}{(1.054)^7})\\\\=\frac{277,000\times 100 }{5.4} \times (1-\frac{1}{1.44})\\\\=\frac{277,000\times 100 }{5.4} \times (1-0.7)\\\\=277,000 \times 100\times 0.055\\\\=\$15,23,500\\[/tex]
