Scenario 1) Before: Y --> 2 R, X--> 2 B. After: Y -->R-B, X--> R-B
Scenario 2) Before: Y --> R-B, X--> 2 B. After: Y -->R-B, X--> 2 B [they exchange Black pieces]
Insuff

Arj,

Is not it ans C.

the stem says that each of which was either red or black and as per opt2, after the exchange ,bowl Y contained 1 jelly bean of each color . So if y as 1-r and 1 B. X should have 1R and 1 B. Am I right?

But if X=The GRE Big Book and Y=rr then after the exchange Y=X=rb. Therefore, two solutions are possible for the exchange.

Agree with Official Guide, answer is (e)
