If one servant is telling the truth, 3 servants would lie. Therefore 7×7=21, and take the different answers minus 21. The remaining nuber should be 6 or 8. 27-21=6, so the answer is green.

Just take the three answers minus 21(at most) and that will give you 4,5,6 and 7 Since he has no '4 and 5' servants, then it can only be 6 or 7. 7 always lies, so the answer is six which is the green servant
Dear Tze Xin, Her explaination is only 1 servent will only tell the truth and the other 3 will tell lies. The text said that sevent which only have 7 legs will tell lie so find how many servent legs who lied (7x3=21). In the text it also said that servent who tell truth either have 6 or 8 legs.To find the truth servent you can either add 21 + 6 or 21 +8 but 21 +8 will give you 29 which is not in the "altogether we have __ legs" but 21+6 = 27 which is the green servent

DeleteBecause there was 3 liars and all liars have 7 legs
