Both together complete the wall in x min.

∴ In one minute both together will complete 1/x part of the wall.
B completes the wall in (x + 5) min

∴ In one minute he will complete 1/(x + 5) th part of the wall.

A completes the wall in (x + 45) min

∴ In one minute he will complete 1/(x + 45) th part of the wall.

Hence, {1/(x + 5)} + {1/(x + 45)} = 1/x

On solving, we get x² – 152 = 0
Hence x = 15.

Thus, working together, they can paint the four walls in 4 × 15 = 60 minutes or 1 hour.

Solve the following question and mark the best possible option.The fou...

Let's assume that it takes A and B together to paint the first wall in x minutes.
On the first day, A and B together paint the first wall in x minutes.
On the second day, B paints the second wall in 5 minutes more than the time taken to paint the first wall, which is x + 5 minutes.
On the third day, A paints the third wall in 40 minutes more than the time taken to paint the second wall, which is x + 5 + 40 = x + 45 minutes.

Therefore, the total time taken to paint the four walls would be:
x + (x + 5) + (x + 45) = 3x + 50 minutes.

Since the four walls have equal dimensions, the time taken to paint each wall would be the same. So, we can assume that x minutes is the time taken to paint each wall.

Therefore, the total time taken to paint the four walls would be 3x + 50 minutes.

To find the value of x, we can use the fact that the total time taken to paint the four walls would be the same as the time taken by A and B together to paint the four walls.

So, 3x + 50 = 4x.

Simplifying the equation, we get x = 50.

Therefore, the total time taken by A and B together to paint the four walls would be 4x = 4 * 50 = 200 minutes.

So, the correct answer is d) 1 hour.

Read the passages carefully and answer the questions that follow :Time has many dimensions, is a concept often advanced to account for certain inexplicable happenings. The gist of the idea is that time - which seems to unfold in a linear way, with the past coming before the present and the present before the future - might, in another dimension, not be experienced sequentially. The past, present and future could exist simultaneously.The concept that there are unfamiliar dimensions of time is most easily approached by way of those dimensions with which we are already familiar, those of length, height and breadth. These, in turn, are best approached, quite literally, from a starting point, which, geometrically speaking, has a location but no dimensions. It does, however, relate to figures with dimensions in the following way: If a point is moved through space, it marks a line, with the one dimension of length. If a line is moved through space, it traces the figure of a plane with the two dimensions of length and breadth. And, if a plane is moved in space, it traces a figure with the three dimensions of length, breadth and height.We can also work backward to form a three-dimensional body and find that the cross section of the three-dimensional cube is a two-dimensional plane, the cross section of the two-dimensional plane is a one-dimensional line and that the cross section of the line is a dimensionless point. From this, we can infer that a body of three dimensions is the cross section of a body, when moved in a certain way, of four dimensions. Then comes the question, of what sort of body could a three-dimensional shape be the cross section? And, in what sort of new direction could a three-dimensional shape be moved to produce one of four dimensions, since a movement other than up and down, backward and forward or side to side would simply produce a larger figure, not one of a different dimension. The answer, of course, is the feature duration. For, as soon as something ceases to endure, it ceases to exit. To the three familiar dimensions, then, we should add duration in time as a fourth dimension. Ordinary, three-dimensional bodies should, therefore, be properly described as having only length, breadth and height but no duration. Is such a thing possible? It is, but only hypothetically. For in fact, the point, line and plane do not truly exist as such. Any line that can be seen has breadth as well as length (and duration), just as any physical plane has a certain thickness as well as length and breadth. What movement, then, must a figure of three dimensions undergo to produce a body of four dimensions?We moved a plane in the dimension of height to produce a cube, so the movement of a (hypothetical) cube in the dimension of time should produce a (real) figure of four dimensions. What does movement in the dimension of time mean? As we said, it must mean movement in a new direction, not up, down or sideways. Are there any other kinds of movement? For a start, there is the movement that the Earths rotation imparts to everything upon it and that puts even apparently motionless bodies in motion. Thus, we may say that the cross section of a real body, whose fourth dimension is duration, is inseparable from the motion that the turning world inevitably imparts to everything. Further, inevitable motions are that of the Earth around the Sun, of the Sun around the centre of the galaxy, and, perhaps, of the galaxy itself around some unknown point. Since any perceptible body is, in fact, undergoing all these motions simultaneously, we can say that it is ordinarily imperceptible. Because, motions and the dimensions, they imply, are only perceptible in a framework of time, they can be referred to as dimensions of time.If duration is one aspect of time, what might the others be? Among several possibilities, we can suggest appearance and disappearance, change and recurrence. Of all possibilities, only duration is perceptible. When we say that something is perceptible, we mean that we suddenly note its existence, when something disappears we note its lack of existence. We perceive no intermediate condition of appearing or disappearing. In the same way, we talk of change, but actually only develop the concept, as we perceive aggregates of characteristics that exist or cease to exist. And so we infer, but do not observe, the recurrence of sunset and sunrise, the passage of seasons, the growth of a child. And yet, things really do appear and disappear, change and recur, although not actually perceived to do so. They are, so to speak, hypothetical to us and must have their reality in other dimensions of time, just as the hypothetical three-dimensional body becomes real, that is, perceptible, in the dimension of time we call duration.If access to higher dimensions of time belongs to one body, it is at least theoretically possible that it belongs, though invisibly, to all bodies. We can further assume that such access is by way of unfamiliar modes or levels of consciousness – and that the name we give to one of these is prophecy.Q. The author mainly agrees with the idea that

Directions for Questions: The first-year students in a business school are split into six sections. In 2019 the Business Statistics course was taught in these six sections by Annie, Beti, Chetan, Dave, Esha, and Fakir. All six sections had a common midterm (MT) and a common end term (ET) worth 100 marks each. ET contained more questions than MT. Questions for MT and ET were prepared collectively by the six faculty members. Considering MT and ET together, each faculty member prepared the same number of questions.Each of MT and ET had at least four questions that were worth 5 marks, at least three questions that were worth 10 marks, and at least two questions that were worth 15 marks. In both MT and ET, all the 5-mark questions preceded the 10-mark questions, and all the 15- mark questions followed the 10-mark questions.The following additional facts are known.i. Annie prepared the fifth question for both MT and ET. For MT, this question carried 5 marks.ii. Annie prepared one question for MT. Every other faculty member prepared more than one questions for MT.iii. All questions prepared by a faculty member appeared consecutively in MT as well as ET.iv. Chelan prepared the third question in both MT and ET: and Esha prepared the eighth question in both.v. Fakir prepared the first question of MT and the last one in ET.
