There is a 6 X 6 and a king is placed on the bottom left corner square.In how many ways can the king reach the bottom right corner in exactly five moves?(In one move,chess king can move 1 space horizontally,vertically or diagonally from the sqyare it occupies)
(Spam, kinda)
Anyone in possession of any material/s related to Set Theory,(the maximum and minimum ones and also the diagrammatic ones where there are 4 or more variables to deal with).
Please share.

John is in a room of dimensions 10 m x 10 m. He is standing at the center of one of the walls. Suddenly the walls of the room start closing in on him. All four walls move towards the center of the room at a uniform rate of 10 cm/sec. The dimensions of the walls are adjusted magically according to the new size of the room at each moment. As soon as the walls start moving, he frantically runs from the center of one wall to the next (if he is standing at the east wall, he runs to the north, then west, then south and then back to the east wall). He keeps doing this till the room completely closes in on him. Assume that the dimensions of John are negligible and that he runs at a speed of 5 m/sec. How much distance (in meters) would he have run before he is killed?
You have two beakers with capacities of 4 liters and 5 liters respectively. You also have a tap which you can use at max 2 times to fill any one of the two beakers. (You cannot leave the tap running.) You want to water a plant with exactly 7 liters. What is the least amount of water (in liters) that you will need from the tap to accomplish this task?
The Clinton v/s Trump war has taken a new turn. Each of them is planning to use a number of posters to campaign and the one who has more posters has better chances at winning. Hillary manages to get a hand on 6 posters of trump. They are numbered 55,31,39,23,47,15. Hillary also believes that this is a fairly “well-distributed sample” with respect to the population (which is obviously numbered 1 to N). Using this data, what is the closest estimate she can make of the total posters that Trump is going to use?
Off topic.....How are the Handa ka Funda mocks for CAT ?
In an exam every question correctly answered fetches 2 marks.

In a aeroplane, the fuel burnt is directly proportional to the square root of its speed. If the aeroplane travels 800 km at a speed of 441 km/hr, the amount of fuel burnt is equal to 1250 litres. Find the distance travelled by the aeroplane, if 2000 litres of fuel was burnt while travelling at 784 km/hr.
((Explanation please))

Consider a circle with radius 5cm diameter is PQ while QR is tangent to circle touching circle at point Q. PR intersects circle at point T(PT is a chord ) . TS is tangent to circle touching circle at T. if PT is 8cm what is RS?
A lent B Rs. 900 for a certain time at a certain rate percent per annum, which is equal to the square root of the number of the months of the time. After the time B wanted to return the money, but A instead of taking the interest which amounted to Rs. 48 asked for a certain sum of money at the same rate for a certain number of years which is equal to the square root of the rate percent. Find the sum of money so that none of them should be the loser.
