In the division calculation 952 473 Ã· 18, which two adjacent digits should be swapped in order to increase the result by 100?

If after division by 18 the number has to be increased by 100, then before the division it needs to be increased by 18 Ã— 100 = 1800. So we need to find two adjacent digits in the number 952 473 which when swapped increase it by 1800. If 952 473 is increased by 1800 it becomes 952 473 + 1 800 = 954 273. We obtain 954 273 from 952 473 by swapping the adjacent digits 2 and 4.

The sum of age 5 children born at the interval of 2 year each is 40 year. Find out the age of eldest child?

let's age of youngest child = x

Then the age of 5 children can be written as x,( x + 2) ,(X + 4 ),(x + 6) and( X + 8).

Age of elders child = X + 8

Then ,

X + (X + 2 )+ (X+ 4) +( X + 6) + (X + 8) = 40

5 X + 20 = 40

5 X = 40 - 20

X = 20 / 5

X = 4

Age of elders child = X + 8

4 + 8 = 12.

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 _ bc _ a _ bcda _ ccd _ bcd _

The series is aabcd / abbcd / abccd / abcdd.

Thus, a, b, c and d are repeated twice one by one.

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..

The average of four consecutive odd numbers is 43. What is the difference between the highest and lowest numbers.

Let's 4 consecutive odd numbers are:

3, 5, 7, 9

Lowest term is 3 and highest is 9

9-3 =6

So, difference of 6 will remain the same in the consecutive series numbers.

There are 6 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 grand father of F. There are two fathers three brothers and a mother in the group. How many male members are there in the group?

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 4 male..

If A+B means A is the son of B;

A - B means A is the husband of B;

A x B means A is a sister of B,

then which of the following shows the relation Q is the maternal uncle of P?

Option A

Q is the maternal uncle of P means P is the son of the sister of Q i.e

P is the Son of the husband(say B)of the sister (Say R) of Q i.e( P + B - R x Q)
