Although it seems to be Commodore, the answer cannot be determined due to the fact that we are unaware of the break-up of the sales value and volume of companies compromising the other categories.

If we assume the total sales to be 100 in the first year, IBM's sales would go up by 50% (from 28 to 42) contributing an increase of 14 to the total sales value.



Similarly, Apple's increase of 15% would contribute an increase of 2.1 to the total sales value. The net change would be 14 + 2.1 on 100. (i.e., 16.1%)

Question 3

IBM accounts for 28% of the share by value and 10% of the share by volume.



28% of 1650000 = 28 x 1650000/100 = 462000



10% of 1500 = 10 x 1500/100 = 150



Therefore, average unit sale price = 462000/150 = 3080

Total tonnes of transportation by both rail and road is about 31*12/100=3.72 million tonnes and total cost incured 18*30/100=5.4.

Hence required value is 5.4/3.72 which is about 1.5.

Cheapest mode of transport will be the one which will have highest transport volume and comparatively lowest cost. We can figure from the graph that Road have wide gap with very less costs. For Road, Cost=6/22 For Rail, Cost=12/9 For Pipeline=65/49 For Ship, Cost =10/9

Question 9

Time: 00:00:00
