The accountant and lawer work in their offices, while the dentist and doctor work in their nursing homes. The accountant looks after Mukherji’s and Chatterji’s account. Chatterji, dose not know Bannerji, although his nursing home is in the same street as Bannerji’s office. Chatterji is not a doctor. What are the occupations of the four people.

Seven instructors - J,K,L,M,N,P and Q teach management courses at a premium institute in East India. Each instructor teaches during exactly one term ; the first term, the second term, or the third term. The following conditions apply : 1). K teaches during the third term. 2). L and M teach during the same term. 3). Q teaches during either the first term or the second term. 4). Exactly twice as many instructors teach during the third term as teach during the first term. N and Q teach during different terms. 5). J and P teach during different terms.
Q. No. 1:
Which one of the following could be an accurate matching of instructors to terms ?
A :
M: the first term; P : the second term; Q: the first term
B :
J:the third term; L:the third term; P:the third term
C :
L: the first term; N : the second term; P: the third term
D :
J: the first term; M : the third term; N: the second term
Answer: D 1). K -> 3rd term (always) 2). L + M -> Same term (always) 3). Q-1st or 2nd term only (not in 3rd term) 4). N, Q -> not same term 5). j, P -> not same term 6). If 1 instructor in 1st term less than 2 in 3rd and 4 in 2nd term. If 2 instructor in 1st term than 4 in 3rd and 1 in 2nd. Conclusion :: In 1st term -> either 1 or 2 instructor. In 2nd term -> either 4 or 1 instructor In 3rd term -> either 2 or 4 instructor. => Option A is wrong, because if M teaches 1st term than L will also teach 2st term and 3 instructor (i.e L,M, and Q) cannot reach 1 st term. Option B is wrong because J and P cannot teach in same term. Option C is wrong because if L and M teach during 1st term than the place of 2nd term will only for Q, not for N.
Answer: A 1). K -> 3rd term (always)
2). L + M -> Same term (always)
3). Q-1st or 2nd term only (not in 3rd term)
4). N, Q -> not same term
5). j, P -> not same term
6). If 1 instructor in 1st term less than 2 in 3rd and 4 in 2nd term.
If 2 instructor in 1st term than 4 in 3rd and 1 in 2nd.
Conclusion ::
In 1st term -> either 1 or 2 instructor.
In 2nd term -> either 4 or 1 instructor
In 3rd term -> either 2 or 4 instructor.
Q. No. 3:
If exactly one instructor teaches during the second term, which one of the following must be true ?
Answer: C 1). K -> 3rd term (always)
2). L + M -> Same term (always)
3). Q-1st or 2nd term only (not in 3rd term)
4). N, Q -> not same term
5). j, P -> not same term
6). If 1 instructor in 1st term less than 2 in 3rd and 4 in 2nd term.
If 2 instructor in 1st term than 4 in 3rd and 1 in 2nd.
Conclusion ::
In 1st term -> either 1 or 2 instructor.
In 2nd term -> either 4 or 1 instructor
In 3rd term -> either 2 or 4 instructor. => If exactly one instructor teaches during the second term, we get the following :: 1st term -> N + J/N + P/Q + J/Q + P 2nd term -> Q/N/J/P 3rd term -> K,L,M and P/J/N So, we see that only option C is true.
Q. No. 4:
Each of the following contains a list of instructors who can all teach during the same term EXCEPT
Answer: D 1). K -> 3rd term (always)
2). L + M -> Same term (always)
3). Q-1st or 2nd term only (not in 3rd term)
4). N, Q -> not same term
5). j, P -> not same term
6). If 1 instructor in 1st term less than 2 in 3rd and 4 in 2nd term.
If 2 instructor in 1st term than 4 in 3rd and 1 in 2nd.
Conclusion ::
In 1st term -> either 1 or 2 instructor.
In 2nd term -> either 4 or 1 instructor
In 3rd term -> either 2 or 4 instructor. => According to our conclusion, 4 instructor can teach during the same term which is either 2nd or 3rd. If we consider about option(A) and option(C), they can teach in 3rd term including L and M respectively. If we consider option(B) they can teach in 3rd term including K. But when we consider about option (D), they cannot teach 2nd term because of K (K teaches only 3rd term) and 3rd term because of Q (Q teaches either 1st or 2nd term).
Q. No. 5:
If more instructor teach during the second term than teach during the first term, then which one of the following instructors must teach during the second term ?
Answer: B 1). K -> 3rd term (always)
2). L + M -> Same term (always)
3). Q-1st or 2nd term only (not in 3rd term)
4). N, Q -> not same term
5). j, P -> not same term
6). If 1 instructor in 1st term less than 2 in 3rd and 4 in 2nd term.
If 2 instructor in 1st term than 4 in 3rd and 1 in 2nd.
Conclusion ::
In 1st term -> either 1 or 2 instructor.
In 2nd term -> either 4 or 1 instructor
In 3rd term -> either 2 or 4 instructor. => If 4 instructor teach in the 2nd term and in which term 4 instructor will teach there will be L and M certainly.

A company launches eight products—Q, R, S, T, V, W, Y, and Z—in one of the four metros of India. The products were launched one after the other over a period of six months in 2006. The order in which the products were launched is consistent with the following conditions: 1) V is launched before both Y and Q 2) Q gets launched after Z 3) T gets launched before V but after R 4) S gets launched after V 5) R gets launched before W.
Answer: D On the basis of the information, we have some hints : R > W, R >T>V>S, V>Y/Q and Z>Q => Option A is wrong because Y is launched after R, T and V. Option B is wrong because R is launched before W,T,V,S.Y and Q, but not clear about Z. So R is the either 1st or 2nd product to be launched. Option C is wrong because Q is launched after R,T,V and Z.
Q. No. 2:
If Z is the seventh product to be launched, then which one of the following could be true?
Answer: A On the basis of the information, we have some hints :
R > W, R >T>V>S, V>Y/Q and Z>Q => If Z is the 7th product to be launched than Q will be the 8th product. Option B is wrong because T is launched after R but before V,S,Y,Z and Q, but not clear about W. So, the position of T can be either 2nd or 3rd. Option C is wrong because if Z is 7th term than R will be 1st. Option D is wrong the position of V can vary from 3rd to 5th. Option A is right because W is launched after R. So, W can wary from 2nd to 8th.
Q. No. 3:

Answer: D On the basis of the information, we have some hints :
R > W, R >T>V>S, V>Y/Q and Z>Q => If Q is the 5th product to launched than the launching sequence will be : R>T>V>Z>Q where, Z can vary from 1st to 4th.
Q. No. 4:
If R is the second product to be launched, which one of the following MUST be true?
Answer: C On the basis of the information, we have some hints :
