Answers :-


1.  Here, seven friends are: P, Q, R, S, T, V and W Seven  destinations  are:  Delhi,  Chennai,  Hyderabad, Bangalore, Kolkata, Chandigarh and Jaipur. Let us proceed with the following direct information: R  — Jaipur—Monday;  Bangalore—Saturday; P — Chandigarh; S — Kolkata — Friday; W — Delhi With the help of above information we get the following table



Let us use indirect information. Since Q did not leave for either  Hyderabad or  Banglore,  the  above  table helps  us conclude that Q left for Chennai.
Now,  Theft the next day of P’ s departure and on previous day of W’s. According to the above table, P and W did not depart  on  Monday,  Saturday or  Friday. T  did  not  depart on  Monday  or  Friday.
Now P can’t depart on Sunday or Thursday because T did not depart on Monday  or Friday respectively. P can’t departure on Wednesday because W did not departured on Friday.  Hence,  by  elimination,  P left  for Chandigarh  on Tuesday, T left  for its  destination on Wednesday and W left for Delhi  on Thursday. Now look  upon table  II.




Now, since  Tleft for his destination on  Wednesday, it is obvious that T’s  destination is  Hyderabad.
By elimination, V is going to Banglore, and Q left for Chennai on Sunday.
Hence, the above information can be summarised as follow:



1.   (2)

2.   (3)

3.   (4)

4.   (5)

5.   (1)

6. 4; All scooters are vehicles + No vehicle is a four-wheeler = A + E = E = No schooter is a four-wheeler. Hence neither I  nor II  follows.

7. 1; Some pens are pencils (I) –> conversion –> Some pencils are  pens  (I). Hence  I  follows.  Some  pens  are  pencils  + Some pencisl are black = I + I = No conclusion. Hence II does not  follow.

8. 4; All professionals are doctor + No doctor is rich = A + E = E = No professional  is rich –> conversion  –> No rich is professional  (E).

9. 1; I + I = No conclusion. So possibilities are open (hence I follows) but certainties are not (hence II does not follow).

10. 4; All shares are debentures + No debentures is an equity = A + E = E = No share is an equity  –> conversion  –> No equity is a share (E) –> Some equities are not shares (O). Hence I and II does not follow
