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 mathematical 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: A

Explanation

The correct answer is Option 1 i.e. 81.2

Formula Used:

Average of terms =Sum of termsNumber of termsAverage\ of\ terms\ = {Sum\ of\ terms \over Number\ of\ terms}

Explanation:

According to the given question,

The sum of the vehicles manufactured by Company A = (260 + 218 + 224 + 179 + 266  + 348) = 1495

The average value of the vehicles manufactured by Company A = 149561495 \over 6 = 249.16

The sum of the vehicles manufactured by Company B = (307 + 270 + 250 + 289 + 310 + 416) = 1842

The average value of the vehicles manufactured by Company B = 184261842 \over 6 = 307

Now required % = 249.17307×100{249.17 \over 307} \times 100 = 81.2

Hence the required answer is 81.2%.
