Study the following bar diagram and answer the question that follows.

The production (in thousands) of electronic items (TV and LCD) in a factory during the period from 2011 to 2015.

The difference between the average production of LCDs and that of TVs from 2011 to 2013 is :

1000

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
