a)R > Q > P
b)P > R > Q
c)P > Q > R
d)R > P > Q

Solutions: (1 to 3)

1) Answer (b)

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.
Hence option B .

2) Answer (a)

Cheapest mode of transport will be the one which will have highest transport volume and comparatively lowest cost. We can figure out 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
Lowest cost is for road.
