1, the loan period is 6 years, that is, the repayment period is 6 years.

After 2.2 years, it will be operated and profitable, that is, profitable at the end of the third year.

3. Repayment will be started at the end of the third year, paid off in the sixth year, and repaid in four installments. n=4

4. According to the formula P=A(P/A, 6%, 4), the loan amount at the end of the second year is P2.

5. The maximum loan amount at the beginning of this project is P0, P0=P2(P0/P2, i, n). n=2

The final value is the same as the answer.

Problem analysis 1 1:

1, the loan period is 6 years, that is, the repayment period is 6 years.

After 2.2 years, it will be operated and profitable, that is, profitable at the end of the third year.

3. Repayment starts at the beginning of the third year (actually, it starts at the end of the second year), and it will be repaid in five installments in the sixth year. n=5

4. According to the formula P=A(P/A, 6%, 5), it is 1 the loan amount at the end of the year.

5. The maximum loan amount at the beginning of this project is P0, P0=P 1(P0/P 1, i, n). n= 1

The final value is the same as the answer.

I just figured it out, but the method is stupid. I hope it helps you.
