the ages of two person differ by 12 years. 6 years ago the elder one was 3 years as old as younger one. What is the present age of elder person ?

Let age of elder person=x

Age of younger person =x-12

(x-6)=3(x-12-6)

(x-6)=3x-54

-6+54=3x-x

48=2x

x=48/2

In following questions, three sequence of alphabets/numerals are provided which correspond to each other in some way. Find out alphabets/numerals that come in the blank places. Choose the correct option

C _ B _ D _ A _ B B D D 2 _ _ 4 _ 3 4 _ ? ? ? ? _ a _ c b a _ d _ _ _ _

C _ B _ D _ A _ B B D D 2 _ _ 4 _ 3 4 _ ? ? ? ? _ a _ c b a _ d _ _ _ _

Clearly, 2 corresponds to C and 4 corresponds to A.

So, 1 and 3 corresponds to B and D.

Thus, the missing sequence is 1, 1, 3, 3 or 3, 3, 1, 1..

A family consists of six
members P, Q, R, S, T and U. There are two married couples. Q is a doctor and
the father of T. U is grandfather of R and is a contractor. S is grandmother of
T and is a housewife. There is one doctor, one contractor, one nurse, one
housewife and two students in the family.

Which of the following is
definitely a group of male members?

Option (A)

Q, the Doctor, is the father of T. S, the Housewife, is the grandmother of T and hence the mother of Q. Since there are only two married couples one being that of Q, the grandfather of R i.e., U must be married to S. Thus, R and T will be both children of Q and these must be the students. So, P, who remains, shall be the wife of Q and she alone can be the nurse. Thus, U must be the contractor. Clearly, for definite the males are Q, the father and U, the grandfather.
