In 3 hrs the thief has run 120 km. Relative speed of thief and police is 10 kmph. So, police will take 12 hrs to catch the thief and thus the dog will run for the same amount of time (no matter in what direction!)!

Hence, the total distance travelled by the dog is 12*60=720 km!

720 is the total distance covered by dog, the question asks the distance covered by dog in direction of the thief... you have to remove the distance which dog covered coming back to police each time after seeing the thief...

The following table gives the details of the ages and heights of the boys and girls attending a hobby camp. The height (in cm) of each boy/girl is an integer.

Age Group Boys Girls

(Age(A),in years)

A<=10 8(120,130,150) 10(110,130,140)

11<=A<=13 10(130,150,160) 8(120,140,150)

14<=A<=16 6(150,160,180) 6(140,150,170)

A>16 5(170,180,200) 8(150,160,180)

In the above table, the number mentioned outside the brackets in each cell gives the number of boys (or girls) in that age group and the values mentioned inside the brackets give the minimum height, the average height and the maximum height of the persons in that group, in that order.

For example, of the eight boys who are of age not more than 10 years, the minimum height of any boy is 120 cm, the average height of all the boys is 130 cm and the maximum height of any boy is 150 cm.

1)A team is to be selected from the boys in the camp who were of age 13 years or below. If only boys who are 140 cm or more in height can be selected, the number of boys who can be selected is at most.

2)If a team of girls of age 13 years or less is to be selected, with the condition that all the girls who are 130 cm or more in height must be selected, what is the minimum number of girls selected?

Please give your approach while giving the solution.

Find the remainder when 9*5^43 divided by 1000.

Do we have any source to find all sorts of such questions....help will be really appriciated

Please mention your approach while giving the answer...

John, Pete, Tom, George, and Steve are brothers. One day, one of them broke a window. When their father asked them who did it, they gave the following answers:

John: "It was Pete or Tom."

Pete: "It was neither George nor me."

Tom: "Both of you are lying."

Steve: "No, only one of them is lying."

George: "No, Steve, you are wrong."

Then their mother added: "Three of my sons are telling the truth, but I do not believe what the two others said."

My Question is Who broke the window?

They must be tigether so we have 3 subjects that must be arranged:

AEM

AME

EAM

EMA

MAE

MEA

the answer should be !6 * !3 *!2 * !3

the books can be arranged among themselves as

!6 Economics,

!3 on Mathematics

!2 on Accountancy

and !3 among themselves

ok learnt the approach the HCF will be 58 and not 29 so the answer will be 870*638/58^2 = 165

thnx anyway
