Textbook of Algebra and Trigonometry Class XI is published by Punjab Textbook Board (PTB) Lahore, Pakistan. The book has total of 14 chapters.

Our plan is to give lot of Multiple Choice Questions (MCQs) for the above mentioned book. MCQs are very important because most of entry tests, admission tests and job tests consists of only MCQs.$\sqrt{3}$$n$$\sqrt{n}$$\forall a, b, c \in R$$a&lt;b \wedge c&gt;0\Rightarrow ac\geq bc$$a&lt;b \wedge c&gt;0\Rightarrow ac&gt; bc$$a&lt;b \wedge…</description>
