Manoj Ghosh answered
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

  • a)
    1997
  • b)
    1998
  • c)
    1999
  • d)
    2000
Correct answer is option 'A'. Can you explain this answer?

Ishani Rane answered
Percentage change (rise/fall) in the production of Company Y in comparison to the previous year, for different years are:
For 1997 = [(35 - 25)/25x 100]% = 40%.
For 1998 = [ (35 - 35)/35 x 100]% = 0%.
For 1999 = [ (40 - 35)/35 x 100 ]% = 14.29%.
For 2000 = [(50 - 40)/40 x 100]% = 25%.
Hence, the maximum percentage rise/fall in the production of Company Y is for 1997.

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.
