Solution

Both the students who like Maruti and White colour studies in IV standard .Only D studies in VI standard . He likes Green colour and Honda is his favourite car.  Student whose favourite car is Maruti likes Yellow Colour. The student who likes Grey colour, One who likes Jasmine and the one who likes BMW studies in the same standard. Student whose favourite car is BMW studies in II standard.  Student whose favourite car is AUDI does not study in same standard with the student whose favourite car is Ford.(i.e. Student whose favourite car is AUDI studies in II standard as Student having Ford studies in IV standard) B studies in II standard but he does not likes BMW. One who likes AUDI does not like Red colour. F neither likes Grey nor yellow colour. If we combine the above statements, we will get 2 possible cases: Case-1 The student whose favourite car is Ferrari likes Rose. But, while checking Case1 there is no place together for Ferrari and Rose(as Student whose favourite car is Ferrari likes Rose) . So, the Case 1 cannot be possible. Now consider Case2:  F does not like Grey and Yellow colour. Also, he does not like BMW. So, there is only 1 possible place for F.  B studies in II standard but BMW is not his favourite car C does not like Maruti. E and D does not like Lotus
