Saul invests a number of dollars in investment A at i% simple annual interest, another amount in investment B at j% simple annual interest, and a third amount in investment C at k% simple annual interest. If the percent interest rates i, j, and k are in a ratio of 3:2:4, what is the ratio of the average rate of interest on all three investments (taken together) to the interest rate on investment A?

1) The amounts Saul invested in investments A, B, and C are in a ratio of 1:4:5
2) Saul’s three investments total $100,000, while the total amount of money he earns in interest in the first year is $18,600
