In alphabet series, some alphabets are missing which are given in that order as one of the alternatives below it. Choose the correct alternative.

adb _ ac _ da _ cddcb _ dbc _ cbda

The series is adbc acbd abcd dcba dbca cbda.

Thus, the letters equidistant from the beginning and the end of series are the same.

A family consists of six member's 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. What is the profession of P?

Q, the doctor,is the father of T. S, the housewife, is the grandmother of T and hence the mother of W. Since there are only two married couples one being that of Q, the grandfather of R i.e. U must be married of 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. P is the nurse..

A + B means A is the father of B ;

A - B means A is the wife of B ;

A x B means A is the brother of B ;

A Ã· B means A is the daughter of B.

If P x R + Q, which of the following is true?

Option (A)

Look at this series: 21, 9, 21, 11, 21, 13, . . .

What number should come next?

What number should come next?

In this alternating repetition series, the random number 21 is interpolated every other number into an otherwise simple addition series that increases by 2, beginning with the number 9.

In this Series 21 is common random number.

Now add 2 with 9.

9 + 2 = 11

21 is next common number.

11 + 2 = 13

21 is next common number.

13 + 2 = 15.

21 is next common number.

So the answer is 21..

In following question, A number series is given with one term missing. Choose the correct alternative

9 , 12 , 11 , 14 , 13 , x , 15

9 , 12 , 11 , 14 , 13 , x , 15

Alternately we add 3 and subtract 1. Thus,

9 + 3 = 12, 12 - 1 = 11, 11 + 3 = 14

and so on. Missing number = 13 + 3 = 16..

Choose the term which will continue the following series:

P 3 C, R 5 F, T 8 I, V 12 L, ?

P 3 C, R 5 F, T 8 I, V 12 L, ?

Clearly, the first letters of the terms are alternate.

The sequence followed by the numbers is + 2, + 3, + 4, ... .

The last letter of each term is three steps ahead of the last letter of the preceding term.

Thus, the next term would be X 17 0..

A + B means A is the father of B.

A -B means A is the wife of B.

A Ã—B means A is the brother of B.

A Ã·B means A is the daughter of B.

If P Ã·R + S + Q , which of the following is true?

PÃ·R+S+Q means P is the daughter of R who is the father of S who is the father of Q i.e.P is the sister of the father (S) of Q i.e. P is the aunt of Q..

The ratio of two brothers John and Harry is 4 / 5. However if the age of John before 10 years and that of Harry after 10 years then the original ratio is reversed. What is the age of John?

John age is = a and harry= b

given that a /b = 5 / 4

4a= 5 b

4a - 5b= 0.... Equation 1

and also given that a - 10 / b + 10 = 4 / 5

5 a- 50 = 4 b + 40

5a - 4 b = 90.... Equation 2

by solving both equation

a = 50

.
Look at this series: 201, 202, 204, 207, . . .

What number should come next?

What number should come next?

In this addition series,

1 is added to the first number (201 + 1 = 202);

2 is added to the second number (202 + 2 = 204);

3 is added to the third number (204 + 3 = 207);

and 4 is added to the third number. (207 + 4 = 211)

So the answer is 211..
