(#M40001805) TCS QUESTION latest tcs question Keep an EYE

Anna, Bena, Catherina and Diana are at their monthly business meeting. Their occupations are author, biologist, chemist and doctor, but not necessarily in that order. Diana just told the neighbour, who is a biologist that Catherine was on her way with doughnuts. Anna is sitting across from the doctor and next to the chemist. The doctor was thinking that Bena was a good name for parents to choose, but diana cant say anything. What is each person occupation?

Solution

Correct answer would be
Catherine- Doctor
Bena- Author
Anna- Biologist
Diana- Chemist
Explanation:
Anna is sitting acroos Doctor, SO ANNA can't be Doctor, The Doctor was thinking and had an opinion that Bena was good name, so BENA is not doctor, Diana is not commenting/or having an opinion about bena while doctor had an opinion, so DIANA is also not doctor. So only CATHERINE must be Doctor.
Doctor is sitting across the doctor (Catherine), (They must be sitting on the Rectangular table - 2 on each side ), so Diana cant be sitting in the neighborhood of catherine as Diana's neighbor is biologist. So Anna and Diana both are sitting on the other side of the catherine. And so Anna who is neighbor of Diana must be Biologist. Anna is sitting next to chemist, so Diana is chemist. Left out person i.e Bena who has to be neighbor of catherine and Must be author.
