In following questions, three sequence of alphabets/numerals are provided which correspond to each other in some way. Find out alphabets/numerals that come in the blank places. Choose the correct option

C _ B _ D _ A _ B B D D 2 _ _ 4 _ 3 4 _ ? ? ? ? _ a _ c b a _ d _ _ _ _

Clearly, 2 corresponds to C and 4 corresponds to A. So, 1 and 3 corresponds to B and D. Thus, the missing sequence is 1, 1, 3, 3 or 3, 3, 1, 1..

In following questions, one term in number series is incorrect.

Find out the incorrect number

3, 2, 8, 9, 13, 22, 18, 32, 23, 42

Find out the incorrect number

3, 2, 8, 9, 13, 22, 18, 32, 23, 42

The given sequence is a combination of two series:

I. 3, 8, 13, 18, 23 and

II 2, 9, 22, 32,42

The pattern in I is + 5 and the pattern in II is + 10.

So, in II, 9 is wrong and must be replaced by (2 + 10) i.e. 12.

On Thuesday Bloom bought five hats. On Wednesday half of all the hats that she had were destroyed.On Thursday there were only 17 left. How many did she have on Monday?

On Monday n.o of hat =x

On Tuesday=x+5

On Wednesday :x+5/2

bloom left with:

x+5/2=17

x+5=17Ãƒâ€”2

x+5=34

x=34-5

x=29

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

aba _ baca _ ba _ bacaabac _ aca

The series is abac / baca / abac / baca / abac / baca. Thus, the pattern abac, baca is repeated.

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. Who is the sister of T?

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

A test has 20 questions. If Anna gets 90% correct, how many questions did Anna missed?

The number of correct answers is 90% of 20 or 90/100 x 20

90/100 x 20 = 18

Since the test has 20 questions and she got 18 correct answers, the number of questions she missed is 20-18=2

Anna missed 2 question.

.
In following number series, either one term is missing or is incorrect.

Choose correct answer from options 1, 5, 11, 19, 29, 55

Choose correct answer from options 1, 5, 11, 19, 29, 55

The correct sequence is + 4, + 6, + 8, + 10, ....

So, next term after 29 = 29 + 12 = 41.

The term after 41 will then be (41 + 14) i.e. 55.

41 is missing..
