(1) The bar graph represents the import and export (in 100 Crores of rupees) from 1982-83 to 1986-87.
(2) The export is minimum in the year 1982-83 as the height of the bar corresponding to export is minimum in the year 1982-83.
(3) The import is maximum in the year 1986-87 as the height of the bar corresponding to import is maximum in the year 1986-87.
(4) The bars of export and import are side by side. Clearly, it is seen from the bar graph that the difference between the values of export and import is maximum in the year 1986-87.
