GMAT - Data Sufficiency - Sets

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

The range of the numbers in set S is x, and the range of the numbers in set T is 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
(2) Set T consists of 6 numbers

Since all the numbers in set T are also in Set S

range(T) <= range(S)

y < = x

Statement 1

Set S consists of 7 numbers

if extra numbers in set T lie between max(S) and min(S)

we will still have y<=x

Insufficient

Statement 2

Set T consists of 6 numbers

Same as statement 1
Insufficient
 
Combining
Case remains same. y < = x
insufficient.
