Question

Select the correct alternative from the given choices.
John, Johny, and Janardan participated in a race and each won a different medal among Gold, Silver, and Bronze, not necessarily in that order. Each person among them gives two replies to any question, one of which is true and the other is false (in any order). When asked about the details of the medals obtained by them, the following were their replies:
John: I won the Gold medal.
Johny won the Bronze medal
Johny: John won the Silver medal.
I won the Gold medal.
Janardan: Johny won the Silver medal.
I won the Gold medal.

Which among the following is the correct order of the persons who won the Gold medal, the Silver medal, and the Bronze medal respectively?

Options

• John, Johny, Janardan

• Janardan, John, Johny

• Johny, Janardan, John

• Janardan, Johny, John

Answer 1

Each among John, Johny, and Janardan is an Alternator.
Let John's first statement be true and second be false;

	I	II	Medal
John	T	F	Gold
Johny	F	F	Silver
Janardan	T	F	Bronze

Hence, Johny is not an Alternator, which means our initial assumption was false.
Let John's first statement be false and second be true:

	I	II	Medal
John	F	T	Silver
Johny	T	F	Bronze
Janardan	F	T	Gold

Hence, Janardan → Gold medal
John → Silver medal
Johny → Bronze medal.
