Colored Order
Bigmouth Bertha had been given a bag of gobstoppers by her mother to stop her wittering. The bag contained nine colored sweets: three red, three yellow and three green. Bertha removed three sweets from the bag, one at a time. Her brother, Boring Bernard, who was a collector of insignificant detail, noted the following four facts in his diary.
(a) A yellow sweet was not taken out later than a green one and vice-versa.
(b) Only if a yellow was removed later than a red one was a green taken earlier than a red.
(c) A green was not taken earlier than a red and vice-versa.
(d) The first colour was different from both the second and third colours.
What were the three colors in order of removal?
