Direction: Study the following graph and answer the given questions

  1. What was the difference between the average amount invested in raw materials during the given period and the average value of sales of finished goods during this period?
    1. $ 62.5 lakhs
    2. $ 68.5 lakhs
    3. $ 71.5 lakhs
    4. $ 77.5 lakhs
Correct Option: D

From the given bar diagram , we see
Total amount invested in raw materials in given years = 120 + 225 + 375 + 330 + 252 + 420 = 1995
Number of given years = 6

Average of total investment =
Total amount invested in raw materials in given years
Number of given years

Average of total investment =
1995
= $ 332.5 lakhs
6

Total value of sales of finished goods in given years = 200 + 300 + 500 + 400 + 600 + 460 = 2460
Number of given years = 6
Average value of sales =
Total value of sales of finished goods in given years
Number of given years

Average value of sales =
2460
= $ 410 lakhs
6

Difference = Average value of sales - Average of total investment
Difference = 410 – 332.5 = 77.5 lakh
