Answer: Lies between 3% and 4%

Explanation:
Total number of units produced in 2007 is 450 thousands
=> Target in 2008 = 450 x (100 x 20/100)
=> 450 x 1.2 = 540 thousand
=> Deficit = target – actual produced = 540 – 520 = 20
=> Percentage deficit = 20/540 x 100 = 1/27 x 100 < 4% and > 3%

Answer: 40,000

Explanation:
Total number of all the vehicles produced in 2008 = (100 +15/100) x (total number of all the vehicles produced in 2007) = 1.15 x 450 = 517.5 thousand
Production of vehicles A, B, C and D in 2008 = 275(1.1) = 302.5
For the total no of all the vehicles to be 517.5 thousand, number of vehicles of type E which are produced in 2008 = 517.5 – 302.5 = 215 thousand.
Increase over the previous year = 215 – 175 = 40 thousand.

Answer: 4.44 

Explanation:
Percentage of vehicles of type C in the total number of vehicles in 2006
=> = 100/375 x 100 = 26.66%
=> Percentage of vehicles of type C in the total number of vehicles in 2007 = 100/450 x 100 = 22.22%
=> 26.66 – 22.22 = 4.44 percentage points.

Answer: Rs. 2.66 lakh

Explanation:
Percentage decrease in production of vehicles of type B from 2006
=> To 2007 = 25/75 x 100 = 33.33%
=> Price of vehicle B in 2007
=> 2 x 1.33 = 2 x 4/3 = 2.66 lakh
