A.	Product R fetches second highest revenue across products in 2006	B.	Sum of revenue of P, Q and S is more than the revenue of R in 2009
C.	Cumulative revenue of P and Q is more than the revenue of S in 2008	D.	None of the above

Answer and Explanation

Answer:Cumulative revenue of P and Q is more than the revenue of S in 2008

Explanation:
we will check the statements one – by – one
=> Statement (a), for the year 2006
=> Revenue from P = 25 x 9 = 225
=> Revenue from Q = 40 x 4 = 160
=> Revenue from R = 95 x 13 = 1235
=> Revenue from S = 155 x 3 = 465
=> Product R fetches highest revenue. Statement (a) is false
=> Statement (b) For the year 2009
=> Total revenue from P and Q and S
=> 75 x 9 + 40 x 4 + 85 x 3 = 1090
=> Revenue from R = 135 x 13 = 1755
=> Therefore, option (b) is false
=> Statement (c) For the year 2008
=> Cumulative revenue from P and Q
=> (45 + 25 + 40 + 35) x 9 + (95 + 40 + 105 + 60) x 4
=> 145 x 9 + 300 x 4
=> 1305 + 1200 = 2505
=> Revenue from S = (115 + 155 + 165 + 140) x 3
=> 575 x 3 = 1725
=> Option c is true.
