Question

The following 2 bar graphs show the details of price distribution of making a car. One shows the amounts (in million Rs.) invested by Lamborgini in purchasing raw materials for the production of a car over the years and the other shows the value (in million Rs.) of finished car sold by the company over the years.

i)The difference between the amount invested in Raw materials and value of sales of finished car was maximum during which year?

ii) The value of sales of finished goods in 2009 was approximately what percent of the sum of amount invested in Raw materials in the years 2007, 2008 and 2009?

• A. 2006, 51.65
• B. 2007, 48.78
• C. 2008, 45.33
• D. 2009, 42.56

Answer 1

The correct option is B

2007, 48.78

i) Total difference between the amount invested in Raw materials and value of sales of finished car in 2005= 200-145 = 55 million

Total difference between the amount invested in Raw materials and value of sales of finished car in 2006= 300-250 = 50 million

Total difference between the amount invested in Raw materials and value of sales of finished car in 2007= 500-375 = 125 million

Total difference between the amount invested in Raw materials and value of sales of finished car in 2008= 400-330 = 70 million

Total difference between the amount invested in Raw materials and value of sales of finished car in 2009= 600-525 = 75 million

Total difference between the amount invested in Raw materials and value of sales of finished car in 2010= 460-420 = 40 million

Highest among this is for 2007.

ii) The value of sales of finished goods in 2009 = 600 million – (1)

The sum of amount invested in Raw materials in the years 2007, 2008 and 2009= (375+330+525) = 1230 million – (2)

Percentage ratio of (1):(2) = $\frac{600}{1230}$ x 100 = 48.78 %
