Answer all questions. Please go through the guidelines regarding assignments given in the Programme Guide for the format of presentation.

 

1.         Read the passage given below and answer the questions that follow:

India is coming into its dividend as an unusually young country in an unusually ageing market ¾ a young, fresh-faced nation in a graying world. Globally, more people than ever before are entering retirement. In fact, even by the 1980s, the heads of European countries had begun to worry out loud about Europe’s falling population. ‘Europe is vanishing…our countries will be empty.’ The former French President Jacques Chirac had said¾ the continent was becoming a place of ‘old people, living in old house, ruminating about old ideas’.

This trend of an ageing, shrinking population now visible across much of the developed world, is coinciding with India’s experience of a demographic dividend that will last until 2050. This opens up interesting new opportunities for the country, as the challenge of maintaining wealth in ageing societies means that developed markets will have to increasingly outsource their labour requirements. In 2020 India is projected to have an additional forty-seven million workers, almost equal to the total world shortfall. The average Indian will be only twenty-nine years old, compared with the average age of thirty-seven in China and the United States, forty-five in Western Europe and forty-eight in Japan.

An early sign of the immense potential of our human capital has been the growth of India’s IT sector and the rise of ‘transformational outsourcing’ by multinational firms across industries. The country has seen its global profile rise rapidly on the strength of its human capital¾its entrepreneurs, scientists, engineers and management graduates.

India already has the second largest reservoir of skilled labour in the world. It produces two million English-speaking graduates, 15,000 law graduates and about 9000 PhDs every year. And the existing pool of 2.1 million engineering graduates increases by nearly 300,000 every year.

A talented pool of workers, along with abundant capital and investment, presents us with immense opportunities for creativity and innovation, which can in turn lead to rapid gains in productivity growth and GDP.

a)         Answer the following questions:

i                       What is the advantage that India will soon enjoy compared to the western world?  (2)

ii                     What were the two things that were worrying the former French President?    (2)

iii                    Why do you think age is such an important factor for the economic health of a nation?                                                                                                         (2)

iv                   What has been the early visible sign of India’s economic potential?       (2)

v                     Give an appropriate title to the passage and say why you choose it?       (2)

b)         Pick out words from the passage which mean the same as the following:       (5)

i                       An extra benefit that you do not expect to get

ii                     Thinking about something very carefully

iii                    Becoming smaller

iv                   Pertaining to study of population

v                     A person who organizes and operates a business

c)         Find the opposites/antonyms of the following words from the passage:          (5)

i                       Decreases

ii                     Local

iii                    Fall

iv                   Slowly

v                     Restricted

2.         You have been asked to write a report on flexible working hours for your company. You may write for or against this concept. The first paragraph of the report is given. The report should be of approximately 200 words.                                                              (15)

The report concerns the feasibility of allowing members of staff to start and stop work at the times that suit them best; the obvious proviso is, of course, that everyone should still work a total of 40 hours per week, as we do now. The suggestion of flexible working hours was put forward to the directors by certain members of staff, particularly those who have young children at school.

This assignment has eight problems of 40 marks each of 5 marks. All problems are compulsory. 10 marks are for viva voce.

 

Note: The programs are to be written in C/C++ and/or in MS-Excel/Any spread sheet.

 

 

Problem No. 1: Write a programme that generates (three) approximations of the sequence , using the following three schemes (one for each approximation):

(a)

                                    for  n = 1, 2,…….

 

(b)

                                    for n = 2, 3,………

(c)

                                    for n = 2, 3,……

 

Further, make a table of errors for each of the three approximations in the following format for first ten errors (for each)

Problem No. 2: Write a programme that implements (non-pivoting) Gaussian elimination method for solving n linear equations in n variables, that calls procedures

(i)                  upper-triangularisation and

(ii)                back substitutions

(codes of procedures are also to be written).

Use the programme for solving the following system of linear equations:

Problem No. 3: Write a programme that approximates a root of the equation f (x) = 0 in an interval [a, b] using bisection method. The necessary assumptions for application of bisection method should be explicitly mentioned. Use the method to find a root of the equation.

Problem No. 4: Write a programme that approximates a root of the equation f (x) = 0 in interval [a, b] using Gauss-Seidel method. Use the method to solve the system of linear equations given in Q. No. 2 above. You may make assumption for appropriate initial values of the variable.

Problem No. 5: Write a programme that constructs Lagrangian polynomials, for which at most four nodes are given (hence interpolating polynomial will be at most cubic). Using the programme, find Lagrangian polynomial that approximiates f (x) = x3 and the nodes given are . Use the polynomial to approximate value at x = 1.5.

 

Problem No. 6:  Repeat Problem No. 5 for constructing Newton’s Interpolating polynomial (in stead of Lagrangian Polynomial)

Problem No. 7: Write a programme that approximates the derivative of a given (differentiable) function f (x) at x = xo, using forward–difference formula. Using the programme find the derivative of .

 

Problem No.8: Write a programme that approximates the value of a definite integral  using Simpson’s Rule, with M sample points. Find an approximate value of the integral of  over the interval [1, 6].
