Boys in a class sit in 5 rows such that there is 1 boy in 1st row and 1 boy increase in each row (2 in 2nd 3 in 3rd....). Now they are rearranged again in 5 rows, but equal no. of boys in each row, how many boys are in a row:

Look at this series: 58, 52, 46, 40, 34, . . .

What number should come next?

What number should come next?

This is a simple subtraction series.

Each number is 6 less than the previous number.

(58 - 6 = 52), (52 - 6 = 46), (46 - 6 = 40), (40 - 6 = 34),(34 - 6 = 28)

So the answer is B = 28..

The present ages of Lewis and Brown is 1:2. Three years from now their ages be in ratio 3:5. Find the age of Brown after 5years?

Let

Brown=b

Lewis=l

Present ages be b/l=1:2

2l-b=0....eq(1)

After three years l+3/b+3=3:5

5l-3b=6

By resolving eq

b=12

l=6

After 5 years l= 11

b=17

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.

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 a daughter of B.

If p x R - Q which of the following is true?

P x R-Q means P is the brother of R who is the wife of Q i.e. p is a brother in law of your Q..

A. P. C. D. E and F are six members of a family.

One couple has parents and their children in the family.

A is the son of C and E is the daughter of A.

D is the daughter of F who is the mother of E.

What lationship do D and E bear to each other?

E is an daughter of A and F is the mother of E. So A is the father of E and hence the husband of F. Now, D is the daughter of F. So, D and E are the daughters of A and F. Also,A is the son of C. Now, only B remains. Thus, B and C are the parents of A. Clearly, D and E are sisters..

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

a _ cacbc _ baca _ _ b

The series is abcac / bcaba / cabcb. Thus, the series consits of three sequence. The first three letters of each sequence are in a cyclic order and the last two letters of each sequence are the same as the first and third letters of the sequence.
