Study the line graph and answer the question that follows.
The line graph represents the number of vehicles (in thousands) manufactured by two automobile companies A and B over the years from 2010 to 2015. The X-axis represents the years and the Y-axis represents number of vehicles in thousands.
(The data shown here is only for matematical exercise. They do not represent the actual figures of the country.)
The average value of the vehicles manufactured by Company A is what per cent of the average value of the vehicles manufactured by Company B during 2010 to 2015?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 81.2%.
Average = Sum of all observations/Number of obsevations
The total value of vehicles manufactured by company A during 2010 - 2015 = 260 + 218 + 224 + 179 + 266 + 348 = 1495
Average value of vehicles manufactured by company A during 2010 - 2015 = 1495/6 = 249.16 (in thousands)
The total value of vehicles manufactured by company B during 2010 - 2015 = 307 + 270 + 250 + 289 + 310 + 416 = 1842
Average value of vehicles manufactured by company B during 2010 - 2015 = 1842/6 = 307 (in thousands)
The required percentage = 249.16/307 × 100 = 81.2%
