1.There are as many blue beans as there are red beans
2.The bag contains 15 jelly beans.
Target question:
How many pairs of matching colored beans are there in the bag?
Statement 1: There are as many blue beans as there are red beans
There are several scenarios that meet this condition. Here are two:
Case a: 1 red, 1 blue, 1 green and 12 yellow, in which case
there are 6 pairs
Case b: 2 red, 2 blue, 2 green and 9 yellow, in which case
there are 7 pairs
Since we cannot answer the
target question with certainty, statement 1 is NOT SUFFICIENT
Statement 2: The bag contains 15 jelly beans.
There are several scenarios that meet this condition. Here are two:
Case a: 1 red, 1 blue, 1 green and 12 yellow, in which case
there are 6 pairs
Case b: 2 red, 2 blue, 2 green and 9 yellow, in which case
there are 7 pairs
Since we cannot answer the
target question with certainty, statement 2 is NOT SUFFICIENT
Statements 1 and 2 combined:
There are several scenarios that meet both conditions. Here are two:
Case a: 1 red, 1 blue, 1 green and 12 yellow, in which case
there are 6 pairs
Case b: 2 red, 2 blue, 2 green and 9 yellow, in which case
there are 7 pairs
Since we cannot answer the
target question with certainty, the combined statements are NOT SUFFICIENT
Answer =
E
