(i) In a family of six persons, there are people from three generations. Each person has separate profession and also they like different colours. There are two couples in the family.
(ii) Rohan is a CA and his wife neither is a doctor nor likes green colour.
(iii) Engineer likes red colour and his wife is a teacher.
(iv) Mohini is mother-in-law of Sunita and she likes orange colour.
(v) Vinod is grandfather of Tanmay and Tanmay, who is a principal, likes black colour.
(vi) Nanu is grand-daughter of Mohini and she likes blue colour. Nanu’s mother likes white colour.
What is the profession of Sunita ?
Mohini is mother-in-law of Sunita and grandmother of Nanu. Vinod is grandfather of Tanmay. So, Nanu and Tanmay represent third generation.
Mohini and Vinod form a couple and represent first generation.
Clearly, Roha and Sunita form the other couple and represent second generation.\
Rohan is a CA. Since engineer is married, so Vinod is an engineer and likes red colour.
Mohini is a teacher and likes orange colour.
Nanu likes blue colour.
Tanmay is a Principal and likes black colour.
Sunita, Nanu’s mother, likes white colour.
Clearly, Rohan likes green colour.
The only clue that Sunita, Rohan's wife, is not a doctor, cannot lead to her correct profession. So, the data is inadequate.
