(a) Unscramble following high-level logical reasoning and research methodology terms: i) NALYLTCAIA ii) EFNRECNIE iii) OCNDIUTNI iv) NRBTASACIOT v) SHTESYPHOI. (b) Argument: 'Because many successful entrepreneurs dropped out of college, formal education is unnecessary for achieving high professional success.' Task: (i) Identify the fallacy / faulty reasoning in the statement. Explain how it affects the credibility of the argument. (ii) Narrate how verbal reasoning skills help detect and correct such flawed arguments. (c) A mechanical reasoning scale measures the ability to understand physical principles. Consider a system where two gears (Gear A and Gear B) are interlocked. Gear A has 12 teeth, and Gear B has 36 teeth. (i) Determine the rotation direction of Gear B if Gear A rotates clockwise. (ii) Compute how many complete rotations Gear A must make for Gear B to complete exactly 2 rotations. (iii) Explain how mechanical reasoning scales evaluate a test-taker's ability to generalize such mechanical principles to unfamiliar problems. (d) The average weight of 12 students in a group is 58 kg. When one new student joins the group, the new average becomes 60 kg. Calculate the weight of the new student, showing all steps clearly.

(a) A child went 90 m towards East, and then he turned Right and went 20 m. Subsequently he turned Right and after going 30 m he reached his uncle's house. From there he went 100 m to his North. Determine how far he is from his starting point. (b) The average of 11 numbers is 63, that of the first 6 numbers is 60 and that of the last 6 numbers is 65. Find the 6th number. (c) The following table shows some values of 'x' and the corresponding values of 'y' where y = x³ − 3x − 10: x = -3, -2, -1, 0, 1, 2, 3, 4; y = -28, __, __, -10, __, __, 8, 42. Complete the table and draw a graph between 'x' and 'y' to find the value of 'y' when x = 1.8 and value of 'x' when y = 10. (d) Mr. Raheel invests Rs. 60000 in an account that earns simple interest. At the end of 5 years, the investment is worth Rs. 85000. Calculate the rate of simple interest per year.
