Look at this series: 22, 21, 23, 22, 24, 23, . . .

What number should come next?

What number should come next?

In this simple alternating subtraction and addition series;

1 is subtracted, then 2 is added, and so on.

Rule = (first number - 1), (second number + 2), (third number - 1), (fourth number + 2)....

Now The series is 22, 21, 23, 22, 24, 23, . .

(22 - 1 = 21), (21 + 2 = 23), (23 - 1 = 22), (22 + 2 = 24), (24 - 1 = 23), (23 + 2 = 25)...

So the answer is 25..

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.
