Four persons A B C D were there All were of different weights All Four gave a statement Among the

A says B>D
B says A>C
C says C>D
D says C>B

Since the person with lightest weight tells the truth
C lies (If C tells the truth, then C is not the lightest and then C lies)
===> D>C is the true statement.
So D is also not the lightest person and D lies.
B>C
So from A and B only one is telling the truth and that is not B because
B>C, so B is not the lightest

A is the lightest
A

given:B>D
A>C
C>D
C>B
hence relation is:A>C AND DB>D
SO,D IS the lightest..because C lies between B and D and A>C so..

D is the lightest..

One of the four persons are right then others say rong or opposite.
If a is right b,c,d are opposite to truth
a says B>D is truth
b says A>C opp is C>A is truth
c says C>D opp is D>C is truth
D says C>B opp is B>C is truth

Finally we get B>D>C>A is the answer . A tells truth who is lighter

A is the lightest
A
10 years agoHelpfull: Yes(6) No(4)
A: B>D
B: A>C
C: C>D
D: C>B
now, suppose A is telling the truth, then B>D , C>A , D>C , B>C
according to that, B>D>C>A
hence, A is the lightest, & A is telling the truth..

PS: we have to use the trial and error method here...
