- First assume that all are true, now you get BDCAE which means B and D lied, now position according to the lies, again you get two lairs in front,again rearrange until finally all satisfy. The ans is BCEAD.

- as according to given reply , order is BDCAE . but its given that 1st and 2nd have lied so it means B is not first and C is not third . others are true so answer is CDBAE.
Ans : CDBAE - 12 years agoHelpfull: Yes(4) No(2)
- This is a good case of supposition and contradiction method to solve such problems.
Suppose A is to find its place as 1st or 2nd, then He must lie but the statement that He is not the last will become true, and thus A can never come at 1st or 2nd place.
Out of 4 left i.e B,C,D,E, 6 sets viz BC, BD, BE, CD, CE, ED can come at 1st and 2nd
In case of
BD: Then D, B are to be liar, D said B is in 1st place , it means B is in 2nd place and thus 1st place is for D, but as rest of the people are to be correct E must be correct which says D is not the first. SO contradiction.
Likewise All the cases can be supposed and contradicted, only at 1st place and 2nd place B,C can come, so D has to be true and thus B comes 1st,
So the correct order is

B E C A D. From answer we check the given directions then we observe the required answer is correct.. - 12 years agoHelpfull: Yes(1) No(0)

A&E is in a order
B is first and C is third there is one position between them. We cannot include A&E in that place. Second position is D`s
the order is B,D,C,A,E - 13 years agoHelpfull: Yes(0) No(0)
