Luis said Steve got D and Tom got C.
Determine the correct grades of each student, if each student said one true
and one false statements.​

Answer 1

Answer:

Steve = D

Billy = A

Tom = B

Luis = C

Answer 2

Answer:

Steve- D, Billy-A, Tom -B, Luis-C

Step-by-step explanation:

We need to find correct grades of each if each student said one true

and one false statements.​

Now , Steve told :- Steve: B and Billy: A

          Billy Told :- Billy :C and tom: B

          Tom Told:- tom-A and Luis:C

          Luis told:-  steve: D and Tom: C  

Now if Steve told correct about Billy and wrong about himelf then Billy:A grade and let Steve get D grade.

Now as we considered Billy got A grade so Billy cant get C and hence Tom would get B grade.

Also as Tom got grade B so tom cant get grade A and thus Luis gets grade C.

Thus we got our answer satisfying the condition that each student said one true

and one false statements.​
