A test paper has 20 multiple-choice questions. Each correct answer is awarded 3 marks but -2 marks are given for every wrong answer. No marks are awarded or deducted for questions that are not attempted. a. Sia attempts all questions. She gets only 12 questions correct. How many marks did she score in this test? b. Rajshree scores 5 marks in a test. If she answers 7 questions correctly, find the number of questions she did not answer correctly, and also the number of questions she did not attempt.

In a class test containing 10 questions, every correct answer is awarded 5 marks, every incorrect answer is awarded (-3) marks, and 0 marks are awarded for every questions not attempted. A student gets 4 questions right, 3 questions wrong, and leaves 3 questions unattempted. What is his score?

Let the straight lines x+y-2=0, 2x-y+1=0 and px+qy-r=0 be concurrent and l_1 and l_2 be the two members of the family of lines 2px+2qy+4r=0 which are nearest and farthest from origin : Now answer the following questions : The eqation of line l_1 is : (A) y=5x (B) y=3x (C) 5y=x (D) none of these

Haemophilia is a sex linked recessive disorder of humans. The pedigree chart given below shows the inheritance of Haemophilia in one family. Study the pattern of inheritance and answer the questions given. (a) Give all the possible genotypes of the members 4, 5 and 6 in the pedigree chart. (b) A blood test shows that the individual 14 is a carrier of gaemophilia. The member numbered 15 has recently married the member numbered 14. What is the probability that their first child will be a haemophilic male ? Show with the help of Punnett square.

This interference film is used to measure the thickness of slides, paper, etc. The arrangement is as shown in fig. For the sake of clarity, the two strips are shown thick. Consider the wedge formed in between strips 1 and 2. If the interference pattern because of the two waves reflected from wedge surface is observed, then from the observed data we can compute thickness of paper, refractive index of the medium filled in wedge, number of bonds formed, etc. Considre the strips to be thick as compared to wavelength of ligth and light is incident normally. Neglect the effect due to reflection from top surface of strip 1 and bottom surface of strip 2. Take L = 5 cm and lambda_(air) = 40 nm . For data in question53 determine the distance of point B from the 20th dark band. Counting of dark point has to start from the contact point.
