Every element of S1 is made greater than or equal to every element of S2 by adding to each element of S1 an integer x. Then x cannot be less than
Explanation:
Since every element of S1 is less than or equal to each member of S2, L will be in S1 and G in S2. For some i (1≤ i ≤ 24), ai = L and for some j (25 ≤ j ≤ 50), aj = G. Every other element of S1 is greater than ai and every other member of S2 is less than aj. Therefore, to make every element of S1 greater than or equal to that of S2, we need to add a minimum of (aj –ai) = G – L.
