Q41. I think:
x = yk + 3
Task: x is divisible by 6 Y/N?
1) x is divisible by 3
. (x,y) = (15,12) --> 15 = 12*1 + 3 BUT 15 is not divisible by 6 --> N
. (x,y) = (12,9) --> 12 = 9*1 + 3 AND 12 is divisible by 6 --> Y
--> Insuff.
2) x < y --> x = remainder = 3 --> N --> Suff.
--> B
Please correct me! Thank you.
Q42. I think
Med = ½(a3 + a4) < 42 Y/N?
1) 41,41,41,41,41,47 --> Med = 41 --> Y
42,42,42,42,42,42 --> Med = 42 --> N
2) 41,41,41,41,41,47 --> Med = 41 --> Y
37,42,42,42,42,47 --> Med = 42 --> N
Note: The question doesn’t tell us that U, V, W, X, Y, and Z are in order.
1) + 2) 41,41,41,41,41,47 --> Med = 41 --> Y (minimum case)
--> C
Is that right? thank you
