Data for Questions 6 & 7 : Raina, Murli, Haiden, Patel, Gony, Balaji and Morkel are seven members in a family, out of whichthere are three females and four males. There are two managers, two lawyers, one teacher, one engineer and one doctor. No lady is either a teacher or an engineer. Haiden is a lawyer and is married to Raina, who is a teacher. Balaji, the engineer, is married to Patel, who is neither a lawyer nor a doctor. No two ladies have the same profession. Murli is the sister of Morkel, who is a manager.
6. What is Gony’s profession?
c) Manager or Lawyer
d) Data inadequate
Explanation: From the clues we can see that no lady is either a teacher or an engineer. Hence these have to be males. Now since Raina is a male, Haiden is a female because Haiden is a lawyer and is married toRaina. Balaji the engineer is married to Patel. Hence Balaji is a male and Patel is a female so Patelcannot be teacher or engineer. It is also given that she is neither a lawyer or a doctor. Thus, she is a manager.
Again, Murli is sister of Morkel who is the manager. Morkel is a male because no two females have the same profession and Patel is a female and a manager. On the same grounds, Murli cannot be lawyer hence she is a doctor. By elimination of clues Gony is a lawyer and a male.
Now let us tabulate all the conclusions in a table:
So, Option (b) is correct
7. Which of the following is the group of males?
a) Raina, Murli, Balaji and Morkel
b) Gony, Balaji, Patel and Morkel
c) Raina, Haiden, Gony and Balaji

Data for Questions 8 & 9 : P, Q, R, S, T, U and V are seven members of a family belonging to three generations. There are twomarried couples—one each of first and second generation respectively. They travel in three different cars—Bentley, Lamborghini and Ferrari so that no car has more than three members and there is at least one female in each car. R, who is a granddaughter, does not travel with her grandfather and grandmother. Q travels with his father T in Lamborghini. U travels with her granddaughter S inBentley. P travels with her daughter in Ferrari.
8. How many female members are there in the family?
d) None of these
Explanation: On the basis of the given clues we get the following information:
Besides this we came to know that R is a female but we still do not know the gender of V. But it is given that there is at least one female in each car. The above table shows that Lamborghini has a vacant seat for a female passenger. Hence, the seventh person must be a female to fulfill the condition. Hence, V is a female. But we still do not know in which car R and V are travellingknowing that both are not in the same car. Now we need to construct a family tree:
Since R does not travel with her grandfather and grandmother, R is not in Bentley, hence R is inLamborghini. We are still not aware of V’s position in the family tree.
Option (c) is correct
