Can you arrange the six given marbles in a manner that each one of them is touching all four marbles of different colors?
To make it happen, you must arrange the marbles as the vertices of an octahedron. See the image for reference.
A pet show was happening in my locality. I went down along with my kids. In that show, I noticed that all except two of the entries were cats. All except two were dogs and all except two were fishes.
Can you find out how many of each animals were present in that pet show?
one dog, one cat and one fish
Just muse at the statements with more concentration. All except two were dogs and all except two were cats. Thus we can fairly assume that two animals were not dogs and two were not cats. Now one of that animal that is not dog can be a cat. Similarly one of that animal that is not a cat can be a dog. If we combine this result with the fact that all except two of the pets were fish, we can come up with the result that in that pet show that day, there was one dog, one cat and one fish.
A ship is sailing in the water. It has a rope ladder hanging over its side. The rungs are 355 mm apart. Suppose if the water is rising one meter every 12 hours, how many rungs will be underwater after one day ?
It does not matter how much apart are the rungs as no matter at how much speed the water level rises, none of the rungs will go underwater. This is because with the water level rising, even the ship will be rising. Thus none of the rungs go underwater.
As you can see that fifteen matches have been used to form an arrangement. What you have to do is remove any six of them to make them ten.Can you do that?
Look at the image and see how we did it.
In a science lab, a petri dish hosts a healthy colony of yeast for an experiment. Now every minute, all the yeast cells divide into two. At noon, there was just a single cell of yeast and at 1:22, the Petri dish was half full. Can you calculate when the dish will be full of yeast?
Since at every minute, the cells of yeast are multiplying into two and at 1:22, the dish was half full, it will become full the very next minute i.e. at 1:23.
Can you find out which triangle will have a bigger area among the following?
1. A triangle with sides 300, 400 and 500
2. A triangle with sides 300, 400 and 700
1st
The first option will have a bigger area. This is because the second triangle is not possible.
According to the formula:
Side 1^2 + Side 2^2 = Side 3^2
One day, a class teacher was told that the school superintendent will be visiting her class on the next day. The superintendent can ask questions from anywhere and it can be easy as well as difficult. The teacher will have the liberty to choose any pupil for answering the question.
Now she is determined that the impression that is cast upon the superintendent after the inspection should be great. How will she instruct the students so that she maximizes the chances of receiving a correct answer for each question? Also, she must create the best impression. How will she do it?
It is quite simple a task. The teacher asked all her students to raise their hands on every question. However, those students who knew the right answer were asked to raise their left hand and those who did not know were asked to raise their right hand. In this manner, she would know who knows the correct answer and will pick the students accordingly. Also, since everybody will raise their hands, the final impression will be great.
Three cars are driving on a track that forms a perfect circle and is wide enough that multiple cars can pass anytime. The car that is leading in the race right now is driving at 55 MPH and the car that is trailing at the last is going at 45 MPH. The car that is in the middle is somewhere between these two speeds.
Right now, you can assume that there is a distance of x miles between the leading car and the middle car and x miles between the middle car and the last car and also, x is not equal to 0 or 1.
The cars maintain their speed till the leading car catches up with the last car and then every car stops. In this scenario, do you think of any point when the distance between any two pairs will again be x miles i.e. the pairs will be x distance apart at the same time ?
Not Possible
As per the question, the middle car is running right now approximately at 50 MPH. Therefore, with time, the distance between them will keep increasing by x miles every hour for a certain time. After that, it will start decreasing between the leading car and the last car till they meet.
Therefore, you will find no point where the distance between the cars is x miles again.
Can you think of any number that if divided in half, becomes zero?
8 is the required number.
Chop it up in the middle and you will get either half as zero.
You are given four following results:
1111 = F
2222 = E
3333 = T
Then, can you find out how to code 4444 ?
sixteen
It is simple.
1 + 1 + 1 + 1 = Four
2 + 2 + 2 + 2 = Eight
3 + 3 + 3 + 3 = Twelve
4 + 4 + 4 + 4 = Sixteen
