How to approach the statement above?


Thanks :

1 is insufficient. Think of 145 or 235 or 415 or 136....
2 is insufficient. You have many options: 789, 234, 567,....

Take the two and it's still insufficient: 235 and 145 are examples, since they both comply to the outlined rules.

So my guess is
E

I would approach this, by giving values to x,y,z. If i can form 2 different three digit numbers using the statements then one could safely assume that its insufficient...

(i) Insufficient - Too many options like 127, 901, 361 etc
(ii) Insufficient - Too many options like 123, 234, 345, 456, 159 etc

Both together - Insufficient - Too many options like 136, 235 etc

So answer is E
