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
-2.298 and -8.702 (to 3 dp)
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.

No two prime numbers satisfy that request.
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.
11 and 62
There aren't any such numbers. 9 and 20 are 11 apart but cannot be manipulated to give the required solution.
