Shahrukh speaks truth only in the morning and lies in the afternoon, whereas Salman
speaks truth only in the afternoon. A says that B is Shahrukh. Is it morning or afternoon and
who is A - Shahrukh or Salman?

1)it is morning and A is shahrukh, but is invalid because Shahrukh speaks truth only in the morning
2)it is morning and A is salman,it may be the answer because Salman speaks truth only in the afternoon and we don,t know what does he speak (truth or lie) in morning
3)it is afternoon and A is shahrukh,it may be possible that he is telling a lie so this may be the answer
4)it is afternoon and A is salman,this must be the answer because Salman speaks truth only in the afternoon.
