+Objective Questions
+-------------------
+
+.. A mininum of 8 questions here (along with answers)
+
+
+1. What argument can be used with savefig to increase the resolution
+   of the plot while saving a plot.
+
+   a. fname
+   #. transparency
+   #. dpi
+   #. format
+
+Answer: dpi
+
+2. The fname argument of savefig has to be always absolute path.
+
+   a. True
+   #. False
+
+Answer: False
+
+3. You are right now in the directory `/home/fossee`, from the
+   following which one is the correct one in-order to save the plot as
+   svg with the filename `plot` to the directory `/home/fossee/sine/`
+
+   a. savefig('/sine/plot.svg')
+   #. savefig('sine/plot.svg')
+   #. savefig('home/fossee/sine/plot.svg')
+   #. All of these
+   #. None of the above
+
+Answer: savefig('sine/plot.svg')
+
+4. Which is the best image format to be used with Latex documents
+   which savefig supports?
+
+   a. SVG - Scalable Vector Graphics
+   #. EPS - Encapsulated Post Script
+   #. PS - Post Script
+   #. PNG - Portable Network Graphics
+   #. None of the above
+
+Answer: EPS - Encapsulated Post Script
+
+5. ``savefig('sine.png')`` saves the plot in,
+
+   a. The root directory ``/`` (on GNU/Linux, Unix based systems)
+      ``c:\`` (on windows).
+   #. Will result in an error as full path is not supplied.
+   #. The current working directory.
+   #. Predefined directory like ``/documents``.
+
+Answer: The current working directory.
+
+6. Study the following code and tell what will happen,
+   ::
+      savefig('cosine.png',facecolor='blue')
+
+   a. Will generate an error as plot statements are missing
+   #. Will generate an error as full path is not specified
+   #. Create a file ``cosine.png`` with blue background at the current
+      working directory.
+   #. Create a file ``cosine.png`` with blue background at a
+      predefined directory like ``/documents``.
+
+Answer: Create a file ``cosine.png`` with blue background at the
+	current working directory.
+
+7. How to save the below plot as ``sine_green_border.png`` with green
+   color border/edge in the current working directory.  The plot is given
+   as,
+   ::
+	x = linspace(-5*pi,5*pi,200)
+	plot(x,sin(x),linewidth=2)
+	legend(['sin(x)'])
+
+   a. ``savefig('sine_green_border.png',bordercolor='green')``
+   #. ``savefig('sine_green_border.png',facecolor='green')``
+   #. ``savefig('sine_green_border.png',edgecolor='green')``
+   #. ``savefig('/sine_green_border.png',bordercolor='green')``
+
+Answer: savefig('sine_green_border.png',edgecolor='green')
+
+8. Given the below code snippet, what does it do?
+   ::
+	x = linspace(-5*pi,5*pi,200)
+	plot(x,sin(x),linewidth=2)
+	legend(['sin(x)'])
+    	savefig('sine.png',format='pdf',papertype='a4')
+
+   a. Save the sine plot in file sine.png as a pdf file in page-size
+      A4 and saves it into the current working directory
+   #. Save the sine plot in file sine.png.pdf in page-size A4 into the
+      current working directory.
+   #. Save the sine plot in a file sine.png in png format with
+      page-size A4 in the current working directory overriding the
+      format argument
+   #. Error in filename and format mismatch.
+
+Answer: Save the sine plot in file sine.png as a pdf file in page-size
+	A4 and saves it into the current working directory
+

+.. has not been taught in the tutorial.]
+
+Larger Questions
+----------------
+
+.. A minimum of 2 questions here (along with answers)
+
+1. Plot a cosine plot from -2pi to 2pi in green color taking 300
+   points. Title the plot as 'Cosine plot' and the legend plot with
+   'cos(x)'. And save the plot as a pdf file with the filename
+   cosine_plot.
+
+2. Plot tan(x) where x varies from -4pi to 4pi in red color taking 600
+   points. Title the plot as 'Tan plot' and the legend plot with
+   'tan(x)'. And save the plot as a svg file with the filename
+   tangent_plot.
