Solutions:

Q1. 5
Solution : No. of products manufactured in 2009 = (52.5) x 10^3
                     No. of products manufactured in 2008 = (47.5) x 10^3
                     Required difference = (52.5 – 47.5) x 10^3 = 5000

Q2. 1
Solution : Req % = (25/35) x 100 = 71.43

Q3. 2
Solution : Req % = [(40 – 30)/30] x 100 = 33.33%

Q4. 3
Solution : Req ratio = (45 – 42.5) : (37.5 – 30) = 2.5 : 7.5 = 1 : 3

Q5. 4
Solution : Req Average = (35 + 37.5 + 42.5 + 45 + 47.5 + 52.5)/6 = 43330
