The difference between the average production of LCDs and that of TVs from 2011 to 2013 is :
Answer & explanation
Correct answer: option 2
Average production of LCDs from 2011 to 2013 = \(\frac{7+9+14 }{3 }\)
= \(\frac{30 }{3 }\)
= 10
Average production of TVs from 2011 to 2013 = \(\frac{6+8+13 }{3 }\)
= \(\frac{27 }{3 }\)
= 9
Difference b/w Average production of LCDS and TVs from 2011 to 2013
= 10 - 9
= 1 ( in thousands)
= 1000
