Answer:
The financial service requires a total payment of $94,800, distributed in 6 annual payments of $15,800. Once said amount has been paid, the company invests said money and after the course of 6 years, pays 4 annual payments of $35,000, that is, a total payment of $140,000. In this way, after 10 years of the first payment by the client, this operation ends with a monetary gain on the part of the client of $45,200 (140,000 - 94,800).
Now, to know how much interest is being offered by this investment, we must perform the following cross multiplication:
94,800 = 100
45,200 = X
(45,200 x 100) / 94,800 = X
4,520,000 / 94,800 = X
47.67 = X
As we can see, this operation offers a return of 47.67% in interests.
