According to the regulations, you absolutely can’t use the right-hand lane on a three-lane motorway (unless told to do so due to lane closure or roadworks), so the correct answer is D - ‘use only the left and centre lanes’. ACB. The official thinking distance for 50 mph is 15 m and the braking distance is 38 m. Add those together and you’ve got the correct answer: B - ‘53 m’. If B is the proper subset of A, every element of B must also be an element of A and also B must not be equal to A. Set Theory Exercise 5 . Here n stands for the number of elements contained by the given set A. Let A  =  {1, 2, 3, 4, 5} and B  =  { 5, 3, 4, 2, 1}. Given the two sets, which statement is true? Free theory test practice questions and hazard perception videos. Write the following set in descriptive form. Thinking distance is the distance your car will move while you’re reacting to a situation and braking distance is how far your car will move while you’re pressing the footbrake. Answer : Let A  =  {1, 3, 5, 6}, B  =  {0, 7}, Check whether A and B are disjoint sets. Determine whether B is a proper subset of A. Multiple choice and true or false type questions are also provided. Let A  =  {1, 3, 5, 7} find the cardinality of power set of A. Write down the elements of: (a) X × Y (b) Y × X (c) X 2 (= X × X) (d) What could you say about two sets A and B if A × B = B × A? Answer : We know that the power set is the set of all subsets. Here you can find objective type Sets, Relations and Functions - Aptitude Questions & Answers Basic Sets, Relations and Functions - Aptitude Questions & Answers questions and answers for interview and entrance examination. At first glance, this might not seem like one of the hardest theory test questions and answers. You should aim to do a lot of these types of theory practice questions because there are so many road signs to memorise and it’s easy to get confused. No. These short solved questions or quizzes are provided by Gkseries. You can only afford to get eight theory test answers wrong if you’re going to pass the theory test. In the given sets A and B, every element of B is also an element of A. But B is equal A. From the information given in the question, we have. Of course, everybody is different and the hardest theory questions for one person might be a piece of cake for another. The first option, ‘not exceed 50 mph’, might look tempting, but in reality, you’re not allowed to exceed 60 mph. of students who like either math or science : Total no. Registered office, Fanum House, Basing View, Basingstoke, Hampshire RG21 4EA. Note that in the second identity, we show the number of elements in each set by the corresponding shaded area. Let A  =  {1, 3, 5, 6}, B  =  {0, 5, 6, 7}, find A Î”  B. Created by. of students who like neither math nor science. This might go against your instinct because many theory practice questions concerning incidents, accidents and emergencies state that it’s best to remove casualties from the car (for example if the vehicle is at risk of catching fire or in imminent danger). That’s the only time you should overtake a vehicle on the left. Asahi_Crystal. students who like Maths or Science subjects : No. Quiz:1 Set Theory. 1 X = {a, c} and Y = {a, b, e, f}. This is a hard theory test question if you’re not too well versed with environmental issues! So, n = 4. So, out of the 4 Indian doctors,  there are 3 men. Gravity. What are the hardest theory test questions and answers? The correct answer is D. There are many different types of assistant dogs who can be recognised by the colour of their jackets, but hearing dogs can usually be spotted by their burgundy or yellow coats. 2 A chess board’s 8 rows are labelled 1 to 8, and its 8 columns a to h. Each square of the board is described by the ordered pair (column letter, row number). The mathematical statement 4CA means: *the C is a symbol not the letter. But you’ll still need to study the highway code and spend some time answering theory practice questions. STUDY. All students, freshers can download General Knowledge Basic Sets, Relations and Functions - Aptitude Questions & Answers quiz questions with answers as PDF files and eBooks. (i) Math only, (ii) Science only  (iii) Either Math or Science (iv) Neither Math nor science. So, the number women doctors attending the conference is 1. (iii) The collection of ten most talented mathematics teachers. Then, the number of subsets = 2 3 = 8.
