Question

Three thieves M, B and V each make one statement; only one statement is true.
M: I am innocent. B: I am innocent. V: B is involved.
Who was involved in the robbery?

• A. M
• B. B
• C. V
• D. Cannot be determined

Hint:

N/A

Answer 1

The Correct Option is A

Assume M is innocent ⇒ M’s statement is true. Then for “only one true”, both B and V must be false.
B false ⇒ B is involved; V false then says “B is involved” is false — contradiction (two truths).
Hence M cannot be innocent ⇒ M is involved (M’s statement is false).
Now either B is innocent (B true, V false) or B is involved (B false, V true) — both satisfy “only one true”.
⇒ The definite culprit is M.
