Because he across second position person.So he get second position.

Assume the number of oranges is A. Then A-1 is divisible by 3, 5, 7 and @So, A-1 is a multiple of 5?? = 315 (note: 9 is also a multiple of 3, so 3 must not be included!). We are looking for a value of N for which holds that 315? + 1 is divisible by 1@After some trying it turns out that N = @This means that the greengrocer has 946 oranges..

A dice.
An explanation: "It's always 1 to 6": the numbers on the faces of the dice, "it's always 15 to 20": the sum of the exposed faces when the dice comes to rest after being thrown, "it's always 5": the number of exposed faces when the dice is at rest, "but it's never 21": the sum of the exposed faces is never 21 when the dice is at rest, "unless it's flying": the sum of all exposed faces when the dice is flying is 21 (1 + 2 + 3 + 4 + 5 + 6)..

The ten statements all contradict each other. So there can be at most one statement true. Now suppose there is no statement true. That would mean that statement 10 indeed would be true, which results in a contradiction. This means that exactly nine statements must be untrue, and thus only statement 9 is true..

The pillars stand next to each other. Which means that the cable goes 8 meters straight down and 8 meters straight up.

Conclusion: The distance between the pillars is zero meters..

36% percentage of the mixture of solution.

Explanation: solid in first solution= 20/100*6=1.2 kg

Solid in second solution=60/100*4=2.4Kg 

total solid in final solution=1.2+2.4=3.6

final volume=10 lit

final mixer %=3.6*100/10=36% 

We will ask him simply while pointing to the left that which direction this is. if he say left than he knave and if he says right he is knight.

On the first day, the snail reaches a height of 5 meters and slides down 4 meters at night, and thus ends at a height of 1 meter. On the second day, he reaches 6 m., but slides back to 2 m. On the third day, he reaches 7 m., and slides back to 3 m. ... On the fifteenth day, he reaches 19 m., and slides back to 15 m. On the sixteenth day, he reaches 20 m., so now he is at the top of the pit! Conclusion: The snail reaches the top of the pit on the 16th day!...

So we r starting with

4 points no of intersection-1

5 " " -3

6 " " " -6

continuing and by induction we have 28 intersection with 12 points.

To find the correct switch (1, 2, or 3), turn switch 1 to 'on' and leave it like that for a few minutes. After that you turn switch 1 back to 'off', and turn switch 2 to 'on'. Now enter the room. If the light bulb is lit, then you know that switch 2 is connected to it. If the bulb is not lit, then it has to be switch 1 or @Now touching for short the light bulb, will give you the answer: if the bulb is still hot, then switch 1 was the correct one; if the bulb is cold, then it has to be switch 3.

Tom takes a piece of fruit from the box with the labels 'Apples and Pears'. If it is an apple, then the label 'Apples' belong to this box. The box that said 'Apples', then of course shouldn't be labeled 'Apples and Pears', because that would mean that the box with 'Pears' would have been labeled correctly, and this is contradictory to the fact that none of the labels was correct. On the box with the label 'Appels' should be the label 'Pears'. If Tom would have taken a pear, the reasoning would have been in a similar way. .

The difference between the real time and the time of the mirror image is two hours and ten minutes (two and a half hours, minus the twenty minutes of cycling).

Therefore, the original time on the clock at home that morning could only have been five minutes past seven: The difference between these clocks is exactly 2 hours and ten minutes (note that also five minutes past one can be mirrored in a similar way, but this is not in the morning!).

Conclusion: The boy reaches school at five minutes past seven plus twenty minutes of cycling, which is twenty-five minutes past seven!.

 

 

If you have written down a full paper of mathematical formulas, you have been thinking too complicated...It is obvious that the cork does not move relatively to the water (i.e. has the same speed as the water). So if the swimmer is swimming away from the cork for half an hour (up stream), it will take him another half hour to swim back to the cork again. Because the swimmer is swimming with constant speed (constant relatively to the speed of the water!) you can look at it as if the water in the river doesn't move, the cork doesn't move, and the swimmer swims a certain time away from the cork and then back. So in that one hour time, the cork has floated from 1 kilometer up stream to the bridge. Conclusion: The water in the canal flows at a speed of 1 km/h..

 

The neighbour borrowed an extra cow, to make the total number of cows 1@Then the oldest son got 1/2 of 18 is 9 cows, the middle son got 1/3 of 18 is 6 cows, and the youngest son got 1/9 of 18 is 2 cows. Since 9+6+2 = 17, the cows could be divided among the three brothers in such a way that the borrowed cow was left over, and could be returned to its owner

72

Explanation : let time taken for each of 150 questions is x

time taken for each maths question is 2x

total time period is 3hr=180min

150x+50(2x)=180

250x=180min

x=180/250=0.72min=43.2sec

time taken for maths problems is 43.2*2*50=72 min

General Gasslefield said:

"I will be shot."

If this statement was true, he would have been hung and thus not be shot. But then his statement would be false, which implies that he should be shot, making the statement true again, etc... In other words: the verdict of the court-martial could not be executed and the general was released..

 

I think Miss Miranda her self is a student so she can give ten apples to her classmates and remaining one she'll have in her bowl for herself.

11/14.

Explanation : Area of the square is 36.divide it into 4 so each square is 9.so the side is 3.radius is 3!!area of the square is 36 and circle is pi*r^2 ie 28.26 the ratio is 11/14.

By putting 8 boxes in a box, the total number of empty boxes increases by 8 - 1 = @If we call x the number of times that 8 boxes have been put in a box, we know that 11 + 7x = 10@It follows that x=1@In total, 11 + 13 × 8 = 115 boxes have been used.

Ans: 6%.

Explanation :30% from maharashtra.

Within 30% the 20%= total 6,so it is 6% for whole 100% students.

 

Let v be the speed of the escalator, in steps per second. Let L be the number of steps that you need to take when the escalator stands still. Upwards (along with the escalator), you walk 1 step per second. You need 50 steps, so that takes 50 seconds. This gives: L - 50 × v = 5@Downwards (against the direction of the escalator), you walk 5 steps per second. You need 125 steps, so that takes 25 seconds. This gives: L + 25 × v = 12@From the two equations follows: L = 100, v = @When the escalator stands still, you need 100 steps.

 Again, the system behind the sequence is that each number (except the first one of the sequence) "describes" the previous number. Now, however, the number of occurrences of each cipher is counted. So 1231 means one "2" and three times a "1", and 131221 means one "3", one "2", and two times a "1". The number following on 131221 is therefore 132231 (one "3", two times a "2", and three times a "1"). The complete sequence is as follows: 1 11 21 1211 1231 131221 132231 232221 134211 14131231 14231241 24132231 14233221 14233221 etcetera .

Answer 1:

In the morning, the 200 kilograms of cucumbers are 99% water. So the non-water part of the cucumbers has a mass of 2 kilograms. At the end of the day, the cucumbers are 98% water. The remaining 2% is still the 2 kilograms of non-water material (which does not change when the water evaporates). If 2% equals 2 kilograms, then 100% equals 100 kilograms. So, the greengrocer has 100 kilograms of cucumbers left at the end of the day..

Answer 2:

198 KG.
