For the years 2014 to 2016, what is the difference (numbers in thousands) between the combined production of computers by Companies A and D and the production of computers by Companies B and C taken together?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. 280.
Difference = (B + C) - (A + D)
The combined production of computers by Companies A and D = Production of A + Production of D
⇒ A + D = (1350 + 570 + 420) + (810 + 990 + 580)
⇒ A + D = 2340 + 2380 = 4720
The combined production of computers by Companies B and C = Production of B + Production of C
⇒ B + C = (750 + 520 + 1170) + (630 + 1280 + 650)
⇒ B + C = 2440 + 2560 = 5000
Required difference
Difference = 5000 - 4720 = 280 (in thousands)
Thus, The difference between the combined production of computers by Companies A and D and that of Companies B and C is 280 (in thousands) computers.
