In a single row of yellow, green and red colored tiles, every red tile is preceded immediately by a yellow tile and every yellow tile is preceded immediately by a green tile. What color is the 24th tile in the row?
(1) The 18th tile in the row is not yellow.
(2) The 19th tile in the row is not green.
Stmnt 1 insuff. 18 could be green or red
Stmnt 2 insuff. 19 could be yellow or red.
Now I'm not sure about this problem... are we suppose to assume that the order is like so Green Yellow Red Green Yellow Red etc...
b/c if not, there is no restriction on the amount of greens. it could be GGGGGGGGGGGGGGGGGGYRGGGGG
if we are to assume GYR, then 18 is Green 19 Yellow 20 is Red. which makes 24 Green.
Wuts OA, my guess depending on the assumptions C or E.
