The numbers are 55.5 and 44.5
let x = first number, y = second. x+y = 155 x-y = 11 add the two equations 2x= 166 x = 83 y = 72
2 x 3 x 5 x 7 = 210 and 7 + 11 + 89 + 103 = 210 The question did not state whether the four prime numbers were to be added, subtracted, multiplied, or combined by some other operation.

There aren't any such numbers. 9 and 20 are 11 apart but cannot be manipulated to give the required solution.
