Question

The production of pens by companies A and B is shown using the line graph below.

Find the ratio of the average pens produced by companies A and B during the years.

• A. 15:11
• B. 13:15
• C. 15:13
• D. 12:13

Answer 1

The correct option is C 15:13

The data of the production of pens by companies A and B can be tabulated:


Total production of pens by Company A = 450,000
Total production of pens by Company B = 390,000

$Averageproduction=\frac{Totalproductionbyeachcompany}{Numberofyears}$

Average production by Company A
$=\frac{450,000}{5}$

$=90,000pens$

Average production by Company B
$=\frac{390,000}{5}$

$=78,000pens$

Ratio of the average production of Company A to Company B
$=90000:78000$

$=15:13$

Thus, the ratio of the average production of pens of Company A to Company B is 15:13.
