Directions : Study the following pie chart and bar chart carefully and answer the questions given beside.

A person covers a total distance of 3000 km in 6 days, by bus, by Ola, and by Uber. Study the pie chart and bar graph to answer these questions.
 
The percentage of total distance travelled in 6 different days.



The percentage of distance covered by each mode on each day.


 
1
What is the total distance covered by Bus?
» Explain it
C
Day Total distance By bus
Day1 25% of 3000 = 750 km 30% of 750 = 225 km
Day2 15% of 3000 = 450 km 25% of 450 = 112.5 km
Day3 20% of 3000 = 600 km 45% of 600 = 270 km
Day4 10% of 3000 = 300 km 20% of 300 = 60 km
Day5 18% of 3000 = 540 km 15% of 540 = 81 km
Day6 12% of 3000 = 360 km 18% of 360 = 64.8 km
    Total = 813.3 km

Hence, option C is correct.
2
If everywhere Ola maintains an average speed of 40 km per hour then what is the total time (In hour) in six days spent on Ola? (approximately) 
» Explain it
C
The total distance travelled by Ola = 1084.2 km

Speed = 40 km per hr

Time =  1084.2  = 27.105 hours = approximately 27 hours
40

Day Total distance By Ola
Day1 25% of 3000 = 750 km 45% of 750 = 337.5 km
Day2 15% of 3000 = 450 km 35% of 450 = 157.5 km
Day3 20% of 3000 = 600 km 15% of 600 = 90 km
Day4 10% of 3000 = 300 km 20% of 300 = 60 km
Day5 18% of 3000 = 540 km 60% of 540 = 324 km
Day6 12% of 3000 = 360 km 32% of 360 = 115.2 km
    Total = 1084.2 km

Hence, option C is correct.
3
The distance travelled by Ola is approximately how much percentage of the distance travelled by Uber? (round off two decimal) 
» Explain it
C
The total distance travelled by Ola = 1084.2 km

The total distance travelled by Uber = 3000 – 813.3 – 1084.2 = 1102.5 KM

The reqd. % =  1084.2 × 100  = 98.34%
1102.5

Hence, option C is correct.
4
Find the respective ratio of the distance travelled by Bus, Ola, and Uber.
» Explain it
A
The distance travelled by bus = 813.3 km 
 
The distance travelled by Ola = 1084.2 km 
 
The distance travelled by Uber = 1102.5 km 
 
The required Ratio = 8133 : 10842 : 11025 = 2711 : 3614 : 3675 

Hence, option A is correct.
5
Suppose, Instead of Bus, the person uses Ola and the speed of Ola is 25% more than the speed of bus then approximately how many hours the person would save? (The average speed of bus is 30 km per hour) 
» Explain it
D
The average speed of bus is 30 km per hour then the average speed of Ola

30 × 125  = 37.5 km
100

The total distance travelled by bus = 813.3 km
The reqd. time =  813.3  –  813.3
30 37.5

= 813.3 ×  7.5  = 5.422 hours = 5.4 hours approximately
30 × 37.5

Hence, option D is correct.
