All these 6 members of a family A, B, C, D, E, F are travelling together. B is the son of C but C is not the mother of B, A and C are a married couple. E is the brother of C. D is the daughter of A. F is the brother of B. Who is the wife of E?

B is the son of C but C is not the mother of B means C is the father of B. A is married to C means A is the 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 of A and C. Clearly from the data available the wife of E cannot be determined..

A family consists of 6 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 house wife and two students in the family.

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

Q the doctor, is the father of T. S, the house wife, 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 student. So P, who remains, Shell 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..

The sum of age 5 children born at the interval of 2 year each is 40 year. Find out the age of eldest child?

let's age of youngest child = x

Then the age of 5 children can be written as x,( x + 2) ,(X + 4 ),(x + 6) and( X + 8).

Age of elders child = X + 8

Then ,

X + (X + 2 )+ (X+ 4) +( X + 6) + (X + 8) = 40

5 X + 20 = 40

5 X = 40 - 20

X = 20 / 5

X = 4

Age of elders child = X + 8

4 + 8 = 12.

Look at this series: 8, 22, 8, 28, 8, . . .

What number should come next ?

What number should come next ?

This is a simple addition series with a random number, 8, interpolated as every other number.

In the series, 6 is added to each number except 8, to arrive at the next number.

In this Series 8 is common number.

Now add 6 with 22 or 28.

22 + 6 = 28

28 + 6 = 34.

So the answer is 34..
