A + B means A is the daughter of B ;

A x B means A is the son of B and

A - B means A is the wife of B.

If Z x T - S x U + P, what is U to Z.

Option: (B)

P is the brother of D. X is the sister of P. A is the brother of F. F is the daughter of D. M is the father of X. Who is the uncle of A?

Option: (B)

A is the brother of F who is the daughter of D. So, A is the son of D. P is the borhter of D. So, P is the uncle of A.

All the 6 member of family A, B, C, D, E and F are travelling together . B is son of C but C is not mother of B, A and C are a married couple. E is brother of C. D is daughter of A. F is the brother of B. How is E related to D?

B is the son of C but C is not mother of B means C is a father of B. A is married to C means A is mother of B. F is brother of B means F is son of A and C. D is daughter of A means D is daughter A and C. E is brother of C who is father of D. So E, is uncle of D..

A family consists of six members P, Q, R, X, Y and Z. Q is the son of R but R is not mother of Q. P and R are a married couple. Y is the brother of R. X is the daughter of P. Z is the brother of P. Which is a pair of brothers?

Option (D)

Q is the son of R but R is not the mother. So, R is the father of Q. P is married to R. So, P is the wife of R and the mother of Q. X is the daughter of P and hence of R and so she is the sister of Q. Y is the brother of R and Z is the brother of P.

Clearly, Y is brother of R who is a male. So, Y and R is a pair of brothers.

What numbers should come next?

This is a simple subtraction with repetition series.

It begins with 20, which is repeated, then 3 is subtracted, resulting in 17, which is repeated, and so on.

Rule = (1st no.), (1st no.), (1st no. - 3 = 2nd no.), (2nd no. repeat), (2nd no. - 3 = 3rd no.), (3rd no. repeat)...

Now in our case, (20), (20), (20 - 3 = 17), (17), (17 - 3 = 14), (14), (14 - 3 = 11), (11), (11 - 3 = 8), (8)...

So the answer is c = 11, 8..

Bombay Express left Delhi from Bombay at 14.30 hours, travelling at a speed of 60 km per hour and Rajdhani Express left. Delhi from Bombay on the same day at 16.30 hours, travelling at the speed of 80 kilometre per hour. How far away from Delhi will the two trains meet?

Suppose they meet x hours after 14.30 hours.

Then 60 x =80 (x-2) or x=8

Required distance=(60*8)km

=480 km.

The average of 6 quantities is 4. The average of 3 them is 3. What is the average of the remaining three numbers?

The average of 6 quantities is 4.

Therefore ,the sum of the 6 quantities is 6 Ã— 4 = 24.

The average of three of these 3 quantities is 3.

Therefore, the sum of these three quantities = 3 Ã— 3 = 9

The sum of the remaining three quantities = 24 - 9 = 15 .

Average of these three quantities = 15 / 3 = 5.
