Tina & Meena are twins. One of them lies while the other is truthful. I asked one of them,

**“Does Tina lie?**” “Yes”, was the answer.

**Did I speak to Tina or Meena?**

See Answer

Answer: He spoke with Meena.

Lets assume both cases

If i ask this question from Meena, answer will be YES in this case and if i ask with Tina, answer will be NO. So in this case i must have asked this from Meena(as YES was the answer).

**How?**Lets assume both cases

**Case 1: If Tina is liar and Meena is truthful**If i ask this question from Meena, answer will be YES in this case and if i ask with Tina, answer will be NO. So in this case i must have asked this from Meena(as YES was the answer).

**Case 2: If Tina is truthful and Meena is liar**

If i ask this question from Meena answer will be YES in this case(as meena is liar) and Tina should have replied NO, so in this case also i must have asked this question from Meena.
