       Re won the Bronze medal.

Re:I won the gold medal.

     Ga won the Bronze medal.

Ga:I won the Bronze medal.

     Sa won the gold medal.

Who among them won the Bronze medal?


A) Sa

B) Re

C) Ga

D) Cannot be determined

Answer:

Option D

Explanation:

1.Assuming Sa always speaks truth.

$Sa\rightarrow Gold$, $Re\rightarrow Bronzee$, $Ga\rightarrow Silver$

Name Statement i Statement II Medal
Sa T T Gold
Re F F Bronze
Ga F T Silver

2.Assuming Re always speaks truth:

Name Statement i Statement ii Medal
Sa F F Silver
Re T T Gold
Ga T F Bronze

Assuming Ga always speaks truth, the first statement of Sa and second statement of Re become true which violates the conditions.

From 1. Re won the Bronze medal.

From2.Ga won the Bronze medal.

So, it cannot be determined
