Download Solution PDFGiven:
The number of computers manufactured by company A during the period from 2010 to 2014:
240, 300, 1250, 470, 320 (in thousands)
The number of computers manufactured by company C during the period from 2010 to 2014:
270, 490, 430, 1180, 550 (in thousands)
Formula Used:
Difference = Total number of computers manufactured by A - Total number of computers manufactured by C
Calculation:
Total number of computers manufactured by company A:
240 + 300 + 1250 + 470 + 320
⇒ 240 + 300 = 540
⇒ 540 + 1250 = 1790
⇒ 1790 + 470 = 2260
⇒ 2260 + 320 = 2580 (in thousands)
Total number of computers manufactured by company C:
270 + 490 + 430 + 1180 + 550
⇒ 270 + 490 = 760
⇒ 760 + 430 = 1190
⇒ 1190 + 1180 = 2370
⇒ 2370 + 550 = 2920 (in thousands)
Difference = 2920 - 2580
⇒ 340
The difference between the number of computers manufactured by company A and C during the period from 2010 to 2014 is 340 thousand.
