A database of research articles in a journal uses the following schema. (VOLUME, NUMBER, STARTPAGE, ENDPAGE, TITLE, YEAR, PRICE) The primary key is (VOLUME, NUMBER, STARTPAGE, ENDPAGE) and the following functional dependencies exist in the schema. (VOLUME, NUMBER, STARTPAGE, ENDPAGE) → TITLE (VOLUME, NUMBER) → YEAR (VOLUME, NUMBER, STARTPAGE, ENDPAGE) → PRICE The database is redesigned to use the following schemas. (VOLUME, NUMBER, STARTPAGE, ENDPAGE, TITLE, PRICE) (VOLUME, NUMBER, YEAR) Which is the weakest normal form that the new database satisfies, but the old one does not?  
Consider the following statements regarding crystal defects: 1. In metals, a self-interstitial introduces relatively large distortions in the surrounding lattice because the atom is substantially larger than the interstitial position in which it is situated. 2. All crystalline solids do not contain vacancies and, it is possible to create such a material that is free of these defects. 3. Impurity point defects are found in solid solutions, of which there are two types: Substitutional and interstitial.  Which of the above statements is/are correct?
A distributor sells TVs at 20% profit per piece. He introduced a new scheme that buyer can buy TVs in bulk and will get (n / 10)% off in the total purchase amount (Where n is the number of pieces in the bulk order). In March he sold 100 TVs in one bulk order and the others were single piece order. If he got an overall profit of 10% in March, how many single piece orders were there in March?
Which dimension defect are interfacial defects?
Let X be a right circular cylinder with height ‘h’ and diameter ‘d’, Y be a right circular cone with height and diameter equal to that of cylinder X and Z be a sphere of maximum volume that can be inscribed in the cylinder X. Consider the following statements: 1. If d < h, then the volume of Y is (h/2d) times the volume of Z. 2. If d > h, then the volume of Y is (d2/2h2) times the volume of Z. Which of the above statements is/are correct?
You install your boot volume on volume C on your Windows 2000 Server computer. You mirror volume C on dynamic Disk 1. Two years later, during routine server maintenance, you open Disk Management and find that the status of volume C is Failed Redundancy. The status of Disk 1 is Missing. You attempt to reactivate Disk 1, but the status of volume C does not return to Healthy. What should you do next?
A senior quality engineer during a training session trains his juniors about a particular common defect that has been found in their assembly. He has formulated a plan which will rectify the defect and ensure that the same defect does not pass further to the customers. Which of the following inference is incorrect?
Each of the question below consists of a question and three statements number I, II and III given below it. You have to decide whether the data provided in the statement are sufficient to answer the question. Two person X and Y together can make 25% of total number of bricks in 4.8 days. Another person Z can make 50 bricks in a day. What is the time taken by person X and Z together to make the total number of bricks? I. Dimensions of a brick is (3cm × 4cm × 5cm) while the dimension of a cuboids when all the bricks are put together is (72cm × 80cm × 50cm) and ratio of number of days taken by X and Y alone to make the total number of bricks is 3 : 2. II. The total number of bricks is 4800 and person Y can make 150 bricks in day. III. Total volume of all the bricks together is 1.008m3 and dimension of a bricks is (5cm × 6cm × 7cm) and time taken by Z to make total number of bricks is 200 % more than the total time taken by person Y to make total number of bricks.
