This chapter is about the Number system in which you will study the types of number system. Natural Numbers, Whole Numbers, Odd, Even, Rational, Irrational, Prime Numbers are the different types of number. The detailed study about the complex numbers is discussed in this chapter. They have different properties and forms. So, this is the brief introduction of this chapter. Every year, the entry test is taken for admissions in different Universities. For this, the students who have passed Intermediate with Maths subject applies for the relevant university and programs. For the admissions, the universities conduct an entry test. The syllabus is included from the text books of the relevant subjects. ECAT is the engineering test and about 30% MCQs are included from Mathematics. Similarly, the entry test like NTS, NET, PU Entry Test, and others have a good weightage of Mathematics portion. So, if you want to prepare for the test, scroll down and get the important MCQs.<\/p>\n<h2 style=\"text-align: center;\">1st Year Maths Chapter 1 Number System MCQs with Answers<\/h2>\n<p><img decoding=\"async\" loading=\"lazy\" class=\"size-full wp-image-426 aligncenter\" src=\"https:\/\/talib.pk\/test-preparation\/wp-content\/uploads\/2020\/09\/Maths-MCQs.jpg\" alt=\"1st Year Maths Chapter 1 Number System MCQs with Answers\" width=\"300\" height=\"300\" srcset=\"https:\/\/talib.pk\/test-preparation\/wp-content\/uploads\/2020\/09\/Maths-MCQs.jpg 300w, https:\/\/talib.pk\/test-preparation\/wp-content\/uploads\/2020\/09\/Maths-MCQs-150x150.jpg 150w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><\/p>\n<p><span style=\"color: #000000;\"><strong><span style=\"color: #ff6600;\">Question#1.<\/span><\/strong><\/span> If &#8216;a&#8217; and &#8216;b&#8217; are real numbers then a + b is a real number.
