In following question, a number series is given with one term missing.

Choose correct alternative that will same pattern and fill in the blank spaces.

7, 6, 10 ,27, 104, ...

Choose correct alternative that will same pattern and fill in the blank spaces.

7, 6, 10 ,27, 104, ...

Here,

7 * 1 - 1 = 6

6 * 2 - 2 = 10

10 * 3 - 3 = 27

27 * 4 - 4 = 104

So 104 * 5 - 5 = 515.

In a hotel 60 people had vegetarian lunch while 35 non vegetarian lunch and 15 had both type of lunch if 90 people were present how many did not eat either type of lunch?

Total people having lunch:

Vegetarian + non vegetarian lunch - both lunch.

= 60 + 30 - 15

=75

People not having either type of lunch

= total people - having lunch people

=90-75

= 15 people who don't have either type of lunch.

There are six persons A, B, C, D, E and F.
C is the sister of F. B is the brother of E's husband. D is the father of A and
grandfather of F. There are two fathers, three brothers and a mother in the
group. How many male members are there in the group?

Option (D)

D is father of A and grandfather of F. So, A is father of F. Thus, D and A are the two fathers. C is the sister of F. So, C is the daughter of A. Since there is only one mother, it is evident that E is the wife of A and hence the mother of C and C and F. So, B is brother of A. There are three brothers. So, F is the brother of C. A, the father, is male. B, the brother, is male. C, the sister, is female. D, the grandfather, is male. E, the mother, is female. F, the brother, is male. So, there are four males.

.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.What is the profession of P?

Option (B)

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. P is the nurse.

Find a five digit number which has no zeros nor ones in it and no digit is repeated,where:

The fourth digit is a quarter of thee total of all the digits, Second digit is twice the first digit,Third digit is the largest and last digit is the sum of the first two digits

Remember the figure must not contain any ones or zeros.

Which term comes next in the series : YEB, WFD, UHG, SKI ?

Clearly, the first letter of each term is moved two steps backward to obtain the first letter of the next term. So, the first letter of the missing term will be Q. The second letter of the first, second, third, fourth terms are respectively moved one, two, three and four steps forward to obtine the corresponding letter of the subsequent term. So, the second letter in the missing term

will be O. The third letter is alternately moved two and three steps forward to obtain the corresponding letter of the subsequent term. So, the third letter in the missing term will be L. Thus, the missing term is QOL. Hence, the answer is (a).The third letters of the first, second, third, fourth and fifth terms are moved seven, eight, nine, ten and eleven steps forward respectively to obtain the third letter of the successive terms. Thus, the missing term would be ZKW. Hence, the answer is (a).

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. Who is the sister of T?

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, R and T are children of same parents. So, R will be the sister of T.

In following questions, a sequence of groups of alphabets and numbers is provided with one term missing , Choose the missing term from options. J2Z, K4X, 17V, ?, H16R, M22P

The first letters in odd numbered terms from series J, I, H and in even numbered terms from the series K, L, M. The sequence followed by the numbers is + 2, + 3, + 4, + 5, + 6. The third letter of each term is moved two steps backward to obtain the third letter of the next term.

.
In alphabet series, some alphabets are missing which are given in that order as one of the alternatives below it. Choose the correct alternative. c _ baa _ aca _ cacab _ acac _ bca

The series is cab / aa / cacab / cacab / aa / cacab / ca. Thus, the pattern cacab, cacab, aa is repeated
