Given below are three quantities named 1, 2 and 3. Based on the given information, you have to determine the relationship between the three quantities. You should use the given data and knowledge of Mathematics to choose between the possible answer. Quantity 1: Area of the innermost square. A square is made by joining the midpoints of a square of area 200 sq. m. The outermost square is called Square 1, The square inside it is called Square 2. The next square is made by joining midpoints of square 2 and is called Square 3. This process goes on. Square 5 is the innermost square. Quantity 2: A man starts with a speed of 10 km/hr. He increases his speed by 10 km/hr every hour at the start and drives at the same speed for that hour. If he traveled a total distance of 550 km. Find the time Quantity 3: Height of cylinder Its volume is equal to the volume of a cone whose radius is 14 cm and height is 39.3 cm. The radius of the cylinder is 14 cm
In the following question the 1st and the last part of the sentence/passage are numbered 1 and 6. The rest of the sentence/ passage is split into four parts and named P, Q, R and S. These four parts are not given in their proper order. Read the sentence/passage and find out which of the four combinations is correct. 1. Security inks misuse a similar rule that causes the clear and always showing signs of changing shades of a film of oil on water. P. At the point when two beams of light meet each other in the wake of being reflected from these distinctive surfaces, they have each travelled somewhat extraordinary distances. Q. The key is that the light is bouncing off two surfaces, that of the oil and that of the water layer beneath it. R. The separation the two beams travel figures out which wavelengths, and thus, meddle productively and look brilliant. S. Since light is an electromagnetic wave, the pinnacles and troughs of each beam at that point meddle either usefully, to seem brilliant, or dangerously, to seem diminish. 6. Since the separation the beams travel changes with the point as you take a look at the surface, diverse hues look splendid from changed review edges.
In which of the following cases, there exists the situation of Pure Bending in some part of the beam or along the entire beam? i) A simply supported beam subjected to two equally spaced downward concentrated loads ii) A simply supported beam subjected to two equally spaced opposite moments iii) A cantilever beam subjected to clockwise moment at free end iv) An overhanging beam with both side overhangs subjected to different concentrated loads at both the free ends
Directions : In each of the following questions a statement is given, followed by two conclusions. Give answer :

Statements : The average number of persons per household is 5 in urban areas whereas it is 7 in rural areas. The national average is 6.

Conclusions :
I. The population per unit area in the rural areas is higher than in the urban areas.
II. More persons live in the same household in the rural areas as compared to those in the urban areas.
Two beams PQ (fixed at P and with a roller support at Q, as shown in Figure I, which allows vertical movement) and XZ (with a hinge at Y) are shown in the Figures I and II respectively. The spans of PQ and XZ are L and 2L respectively. Both the beams are under the action of uniformly distributed load (W) and have the same flexural stiffness, EI (where, E and I respectively denote modulus of elasticity and moment of inertia about axis of bending). Let the maximum deflection and maximum rotation be δmax1 and θmax1, respectively, in the case of beam PQ and the corresponding quantities for the beam XZ be δmax2 and θmax2, respectively. Which one of the following relationships is true?

In the question below, is given a statement followed by three courses of actions numbered I, II and III. On the basis of the information given, you have to assume everything in the statement to be true, and then decide which of the suggested courses of action logically follow (s) for pursuing. Statement: The numbers are impressive. In its quest towards Swachh Bharat, the government has built 4.98 crore rural household latrines in the last three years. What's more, recent surveys by the NSSO and the Quality Council of India show that over 90% people with access to toilets are using them. Launched with the idea of Clean India, it is expanding from urban to the rural areas and is spreading awareness among the masses. Courses of action: I. Given that most rural areas in India lack proper drainage and a sewage network, the government has focused on building twin-pit toilets. But there is no data on whether the size of hastily built twin pits takes into account the number of users, and whether each pit is enough to collect waste for three years.  II. While this is a positive indicator, there are many other areas that need attention such as the shortage of water, sensitization of citizens, proper maintenance and usage of toilets, and overcoming the resistance to dry manure made from human waste.  III. One of the biggest challenges for Swachh Bharat in rural areas is managing liquid waste, which pollutes natural water bodies. Though the scheme covers this aspect as well, the immediate focus is to deal with open defecation.
