  1. In Q(6-10) it is given that E’s bday is exactly between bdays of A and S. But in solution there is 2 bdays in btwn A and E and E ans S. So how come it be ‘EXACTLY BETWEEN’. What I mean is wouldnt there be something like bday of A then bday of E then bday of S in this order? i.e. AES . now if AES is followed other conditions would go wrong.

    1. there are 2 between A and E , also 2 between E and S

      5 between A and S. So middle position is 3rd one na, and E is placed there

      1. I also got it. But then the word should be ‘middle’ not ‘between’. because ‘between’ refers to 1 in between 2.
