DI double Pie Charts

Simple looking Pie charts are not that easy to solve. Pie charts contains two type of questions: Single Pie charts are always easy to solve (See the video below) but multi pie chart can take the toll on your speed as they are speed breakers.

Chart 1 shows the distribution of twelve million tonnes of crude oil transport through different modes over a specific period of time. Chart 2 shows the distribution of the cost of transporting this crude oil. The total cost was Rs. 30 million.

1.What is the cost of transporting petroleum by rail (in Rs)?
1. 2.5
2. 3.33
3. 6.4
4. 8

2.If the cost per tonne of transport by ship, air and road are represented by P, Q and R respectively, which of the following is true?
1. R > Q > P
2. P > R > Q
3. P > Q > R
4. R > P > Q

3. The cost in rupees per tonne of oil moved by rails and happens to be roughly
1. 3
2. 1.5
3. 4.5
4. 8

4. From the charts given, it appears that the cheapest mode of transport is:
2. Rail
3. Pipeline
4. Ship

5.Which is the most effective way of transportation?
2. Ship
3. Pipeline
4. cannot be determined

6.If for some reason ship stop sailing, by what percentage the airfreight have to go up to reach the previous level of volume transported (approximately)?
1. 75%
2. 81%
3. 85%
4 .90%

If the revenue after selling the petroleum was Rs 40 Million and other costs (including oil extraction, marketing etc) is Rs 5 Million, answer the following.

7.What is the Profit percentage?
1. 10%
2. 12.5 %
3. 15%
4. 20%

8. If the cost of transportation rises by 20 % and so does revenue,what is the margin %?
1. 14.08
2. 14.28
3. 14.58
4. 14.78

9.If all costs rise by 10% and revenue remains same ,what would be the decrease in percentage profit?
1. 35
2. 50
3.70
4 .80

10. If the pipeline cost increases by 30% ,by what percentage would revenue have to be increased so as to have same amount of profit?
1. 11.5
2.12.8
3.13.75
4. 14.6

11. If extra 15% tax on transportation costs is added, what would be the effective cost per tonne of petroleum so as to have the same amount of profit as before?
1. 3.2
2.3.5
3.3.7
4. 4.2

1. 2. We get 3.6/1.08=3.33
2. 3 Calculate the cost by ship, air and road.
P = 3/1.08 = 2.77; Q = 2.10/1.32 = 1.58; R = 1.80/2.64 = 0.68 hence P > Q > R
3. 1 3.60/1.08 = 3.33
4. 1 Road is the cheapest, from Q 132.
5. 4 cannot be determined as e do not know on what criteria
6. 2. Air freight is 11% .it would have to increase to 20% i.e. increase by 81.81%
7. 2. 12.5 %
8. 3. 14.58 profit of 7 Million on revenue of 48 Million
9. 3. 70 %
10.4. Pipeline cost is 65%ie 19.5 Million. If this rises by 30 %, it rises by 5.85 Million .to offset this, Revenue would have to rise by the same amount, so 100 = 14.625%
11. 3. 3.7
