The interest of the third investment to have an annual interest earning of 2,709 would be 6,214. This is calculated using the formula: average = (a+b+c ) / 3. By substituting it would be, 2,709 = (1,345 + 568 +x) / 3. Then it would be 8,127 = 1,345 + 568 +x and by transferring the figures, it will be then 6,214.
