Question

n=range(10) denoted number=0,1,2,3,4,5,6,7,8,9.
Then, n=range(5) denoted number=?
n=range(1,10) denoted number=1,2,3,4,5,6,7,8,9
Then, n=range(1,5) denoted number=?
n=range(1,10,2) denoted number=1,3,5,7,9
Then, n=range(10,1,-2) denoted number=?
n=range(2,10,2) denoted number=?
n=range(10,1,-1) denoted number=10,9,8,7,6,5,4,3,2

Answer 1

Explanation:

The range of the numbers in set S is x, and the range of the numbers in set Tis y. If all of the numbers in set T are also in set S, is x greater than y?

(1) Set S consists of 7 numbers. Nothing about set T. Not sufficient.

(2) Set T consists of 6 numbers. Nothing about set S. Not sufficient.

(1)+(2) It's quite easy to get two different answers. For example, if S={1, 2, 3, 4, 5, 6, 7} and T={1, 2, 3, 4, 5, 6}, then x=6>5=y, but if S={1, 2, 3, 4, 5, 6, 7} and T={1, 2, 3, 4, 5, 7}, then x=6=y. not sufficient.
