Draw a bar graph from the above information.

ANSWER:



We can draw the bar graph by following the given steps:

Step 1.- On a graph paper, draw a horizontal line OX as x-axis and vertical line OY as y-axis.

Step 2.- Along OX, write the names of the subjects at the points that are taken at a uniform gap.

Step 3.- Choose the scale:

1 big division = 10 marks

1 small division = 1 mark

Step 4.- Heights of the various bars are:

   Hindi = 43 small divisions = 4 big divisions and 3 small divisions

   English = 56 small divisions = 5 big divisions and 6 small divisions

   Maths = 80 small divisions = 8 big divisions

   Science = 65 small divisions = 6 big divisions and 5 small divisions

   Social Science = 50 small divisions = 5 big divisions

Step 5.- Draw bars of equal width on the x-axis. The difference between the two bars should also be the same.
