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

aab _ ab _ cabcca _ bcab _ c

The series is aa / bcab / bcab / ccaa / bcab / bc.

Thus, the pattern ccaa followed by bcab repeated twice, makes up the series.

Choose the term which will continue the following series : 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 O.

Hence, the answer is (c).

.

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).

.
Which term will replace the question mark in the series :

ABD, DGK, HMS, MTB, SBL, ?

Clearly, the first letters of the first, second, third, fourth and fifth terms are moved three, four, five, six and seven steps forwardrespectively to obtain the first letter of the successive terms. The second letters of the first, second, third, fourth and fifth terms are moved five, six, seven, eight and nine steps forward respectively to obtain the second letter of the successive terms.

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.

There are 6 persons A B C D E and F. C is the sister of F.B is the brother of E' husband. D is the father of A and grandfather of F . There are two fathers three brothers and a mother in the group. Who is E' husband?

D is father of A and grandfather of F. So, A is father of F. Thus, D andbA 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. Clearly, A is E's husband..

K is the brother of N and X. Y is the mother of N and Z is the father of K.

Which of the following statement is not definitely true?

option D.

K is the brother of N and X. So, Y who is the mother of N and Z who is the father of K, will be mother and father of all three .However, it is not mentioned weather N is male or female.
