a)A, B and C are three numbers. Let @ (A, B) = Average of A and B, /(A, B) = Product of A and B, and *(A, B) = The result of dividing A by B.

1) The sum of A and B is given by

a) /(@(A, B), 2)
b) *(@(A, B), 2)
c) @(/A, B), 2)
d) @(*(A, B), 2)
e) None of these

2) Average of A, B and C is given by

a)@(/(@(/(B,A),2),C),3)

b)*(@(/(@(B,A),3),C),2)

c)/(*(*(@(B,A),2),C),3)

d)/(*(@(/(@(B,A),2),C),3),2)

e) None of these

b)There are six persons, P, Q, R, S, T and U, of different heights. Who is the 3rd tallest person? l. S is taller than Q, who is only taller than U. R is taller than T. ll. T is taller than S. R is not the tallest person.

There are two floors between the floors of T and U but neither of them lives on the top floor. The floor of S is immediately above Q’s floor.
The floor of T is above P’s floor.
The floor of P is not adjacent to U’s floor. R’s floor is not the top floor.

d) B*C means B is the son of C.

B^C means B is the daughter of C.

B % C means B is the wife of C.

B $ C means B is the brother of C.

B @ C means B is the husband of C.

If Q is the mother in law of S, then which of the following expression is definitely true?

S * U ^ Q @ R
Q % R * S ^ U
U * S % R * P @ Q
S ^ R % P $ Q
None of these
