Out of the two bar graphs provided below, one shows the amounts (in Lakh Rs.) invested by a Company in purchasing raw materials over the years and the other shows the values (in Lakh Rs.) of finished goods sold by the Company over the years.
Amount invested in Raw Materials (Rs. in Lakhs)
Value of Sales of Finished Goods (Rs. in Lakhs)
The differences between the amount invested in raw material and the value of sales of finished goods for various years are:
For 1995 = Rs. (200  120) lakhs = Rs. 80 lakhs.
For 1996 = Rs. (300  225) lakhs = Rs. 75 lakhs.
For 1997 = Rs. (500  375) lakhs = Rs. 125 lakhs.
For 1998 = Rs. (400  330) lakhs = Rs. 70 lakhs.
For 1999 = Rs. (600  525) lakhs = Rs. 75 lakhs.
For 2000 = Rs. (460  420) lakhs = Rs. 40 lakhs.
Clearly, maximum difference was during 1997.
