Quote:
x is the range of set S, y is the range of set T, T belong to S, x>y?
(1) total numbers in S is 7
s = {1,2,3,4,5,6,7} x = 6
Case 1: T = {2,3,4} y = 2 x > y
Case 2: T = {1,2,7} y = 6 x = y ie. x is NOT greater than y

Quote:
(2) total numbers in T is 6

similarly as in 1 we can take cases here .....

combining also we can have the two cases again.
