1. The total revenue obtained from all the three products was what % higher in 2003 than that in 2002?

(1) 1%                          (2) 0.3%                                    (3) 0.5%                                       (4) 1.5%

Sol 1-6:

1.The total revenue obtained from all the three products in 2003 = Price (Rs) * Sales (in’00).

So, total revenue = [32 * 1500 + 40 * 1200 + 50 * 4500] = Rs. 3,21,000 = 3.21 lacs

Answer: (1)

2.The total revenue from product A for all five years = [ (25*16) + (28*17) + (30*17) +(32*15) + (30*25) ] = 2.62 lacs(approx.).

Answer: (3)

3.It can be seen from the table that Product B revenue was highest in the year 2001.

In 2000, Product B revenue = 64000

In 2001, Product B revenue =126000

In 2002, Product B revenue = 44000

In 2003, Product B revenue = 48000

In 2004, Product B revenue = 45000

Answer: (2)

4.Revenue obtained from product B in 2004 = 45 * 10 = 450 and revenue from product C in 2004 = 52*40 = 2080.

Hence, % increase = (2080 – 450 / 450) * 100 = 362% approx. higher than product B.

Answer: (3)

5.Total revenues in 2002 for all the 3 products = 30*17 + 40*11 + 45*50 = 510 + 440 + 2250 = 3200

Total revenues in 2003 for all 3 products = 32*15 + 40*12 + 50*45 = 480 + 480 + 2250 = 3210.

So, revenues in 2003 were higher by 10 and % increase in revenues = 0.3%

Answer: (2)

1. Revenue obtained from all three products in 2000 = 3.12 lacs, in 2001 = 3.98 lacs, in 2002= 3.2 lacs, in 2003 = 3.21 lacs and in 2004 = 3.28 lacs. Hence the highest revenue from all 3 products was 3.98 lacs in 2001.
