Ans: D

Average production (in 10000 tonnes) over the given years

= $${(25 + 40 + 60 + 45 + 65 + 50 + 75 + 80)} / {8}$$ = $${440} / {8}$$ = 55.

Clearly, the product during 2007, 2008, 2009, 2011 and 2012 are more than the average production. These are 4 years.

Ans: B

Average production (in 10000 tonnes) during 2006 and 2007 = $${(40 + 60)} / {2})$$ = $${100} / {2}$$ = 50.

Average production (in 10000 tonnes) during 2010 and 2011 ⇒ $${(50 + 75)} / {2})$$ = $${125} / {2}$$ = 62.5.

(2009 and 2010) ⇒ $${(65 + 50)} / {2})$$ = $${115} / {2}$$ = 57.5.

(2008 and 2010) ⇒ $${(45 + 50)} /{2})$$ = $${95} /{2}$$ = 47.5.

(2005 and 2009) ⇒ $${(25 + 65)} / {2})$$ = $${90} / {2}$$ = 45.

(2005 and 2009) ⇒ $${(25 + 75)} / {2})$$ = $${100} /{2}$$ = 50.

Average production of 2006 and 2007 = Average production of 2005 and 2011.

Ans: A

Decline percentage from 2007 to 2008

= [$${(60 - 45)} / {60} × 100]$$% = $$({15} / {60} × 100)$$% = 25%.

Ans: B

Ans: B

Percentage increase in production in 2012 compared to 2005

= $$[{(80 - 25)} / {25} × 100]$$% = $$({55}/{25} × 100)$$% = 220%.
