MCQ-> Answer the questions based on the information given below: Madhubala Devi, who works as a domestic help, received Rs. 2500 as Deepawali bonus from her employer. With that money she is contemplating purchase of one or more among 5 available government bonds - A, B, C, D and E. To purchase a bond Madhubala Devi will have to pay the price of the bond. If she owns a bond she receives a stipulated amount of money every year (which is termed as the coupon payment) till the maturity of the bond. At the maturity of the bond she also receives the face value of the bond. Price of a bond is given by: $$P=[\sum_{t=1}^T\frac{C}{(1+r)^{t}}]+\frac{F}{(1+r)^{t}}$$ where C is coupon payment on the bond. which is the amount of money the holder of the bond receives annually; F is the face value of the bond, which is the amount of money the holder of the bond receives when the bond matures (over and above the coupon payment for the year of maturity); T is the number of years in which the bond matures; R = 0.25, which means the market rate of interest is 25%. Among the 5 bonds the bond A and another two bonds mature in 2 years, one of the bonds matures in 3 years, and the bond D matures in 5 years. The coupon payments on bonds A, E, B, D and C are in arithmetic progression, such that the coupon payment on bond A is twice the common difference, and the coupon payment on bond B is half the price of bond A. The face value of bond B is twice the face value of bond E, but the price of bond B is 75% more than the price of bond E. The price of bond C is more than Rs. 1800 and its face value is same as the price of bond A. The face value of bond A is Rs. 1000. Bond D has the largest face value among the five bonds.The face value of bond E must be

MCQ-> Study the information carefully and answer the questions.I, J, K, L, M, N, 0 and P are sitting around a circular area at equal distance between each other but not necessarily in the same order. Some people face the centre while some face the outside (i.e. in a direction opposite to the centre.)J sits third to the right of M. M faces outside. Only one person sits between j and N. Both the immediate neighbours of N face outside. Only three people sit between 0 and P. 0 is not an immediate neighbour of J. Both the immediate neighbours of L face the centre. L is not an immediate neighbour of 0. Both the immediate neighbours of K face the centre. Both the immediate neighbours of M face a direction opposite to that of 0 (i.e. if 0 faces the centre then both the immediate neighbours of M face outside and viceversa.)Which of the following is true regarding I as per the given arrangement ?

MCQ-> Study the following information carefully and answer the questions given below :Eight persons — A, B, C, D, P, Q, R and S — are sitting around a circular table with equal distances between each other (but not necessarily in the same order). Some of them face outside and some others face the centre. NOTE : Facing the same direction means if one faces the centre then the other also faces the centre and viceversa. Facing the opposite directions means if one faces the centre then the other faces outside and viceversa. Immediate neighbours face the same direction means if one neighbour faces the centre then the other neighbour also faces the centre and viceversa. Immediate neighbours face the opposite directions means if one neighbour faces the centre then the other neighbour faces outside and viceversa. P sits to the immediate right of C. Only three persons sit between P and A. R sits third to the left of A. Neither A nor C is an immediate neighbour of B. D sits to the immediate left of B. Q sits second to the left of D. The immediate neighbours of A face the same direction. The immediate neighbours of B face opposite directions. S sits second to the right of P. The immediate neighbours of C face the same direction. S faces outsideFour of the following five are alike in a certain way based on the given sitting arrangement and so form a group. Which is the one that does not belong to that group?

MCQ-> Analyse the following passage and provide appropriate answers for the questions that follow: Each piece, or part, of the whole of nature is always merely an approximation to the complete truth, or the complete truth so far as we know it. In fact, everything we know is only some kind of approximation, because we know that we do not know all the laws as yet. Therefore, things must be learned only to be unlearned again or, more likely, to be corrected. The principal of science, the definition, almost, is the following: The test of all knowledge is experiment. Experiment is the sole judge of scientific “truth.” But what is the source of knowledge? Where do the laws that are to be tested come from? Experiment, itself, helps to produce these laws, in the sense that it gives us hints. But also needed is imagination to create from these laws, in the sense that it gives us hints. But also needed is imagination to create from these hints the great generalizations – to guess at the wonderful, simple, but very strange patterns beneath them all, and then to experiment to check again whether we have made the right guess. This imagining process is so difficult that there is a division of labour in physics: there are theoretical physicists who imagine, deduce, and guess at new laws, but do not experiment; and then there are experimental physicists who experiment, imagine, deduce, and guess. We said that the laws of nature are approximate: that we first find the “wrong” ones, and then we find the “right” ones. Now, how can an experiment be “wrong”? First, in a trivial way: the apparatus can be faulty and you did not notice. But these things are easily fixed and checked back and forth. So without snatching at such minor things, how can the results of an experiment be wrong? Only by being inaccurate. For example, the mass of an object never seems to change; a spinning top has the same weight as a still one. So a “law” was invented: mass is constant, independent of speed. That “law” is now found to be incorrect. Mass is found is to increase with velocity, but appreciable increase requires velocities near that of light. A true law is: if an object moves with a speed of less than one hundred miles a second the mass is constant to within one part in a million. In some such approximate form this is a correct law. So in practice one might think that the new law makes no significant difference. Well, yes and no. For ordinary speeds we can certainly forget it and use the simple constant mass law as a good approximation. But for high speeds we are wrong, and the higher the speed, the wrong we are. Finally, and most interesting, philosophically we are completely wrong with the approximate law. Our entire picture of the world has to be altered even though the mass changes only by a little bit. This is a very peculiar thing about the philosophy, or the ideas, behind the laws. Even a very small effect sometimes requires profound changes to our ideas.Which of the following options is DEFINITLY NOT an approximation to the complete truth?
