Directions: Study the following information carefully and answer the questions given beside:
Four friends, Priyanka, Pinki, Rinki, and Munni start travelling towards a certain distance from the same point and at the same time. The following four pie charts give the information about the percentage of the total distance travelled by them in five different modes of tarvellling i.e on foot, bicycle, Bike, Car and Rickshaw. Each one travels a different distance in the same time.
Priyanka
Pinki
Rinki
Munni
The following table provides information about the distance (in km) travelled by each of them on foot as a percentage of the sum of the total distance travelled by them on foot.
If the average speed of Priyanka is 45 km/hr and the distance travelled by her on foot is 36 km. Find the difference between the average speed of Priyanka and the average speed of Munni?
Suppose Pinki starts 1hour later than all other three start their journey but Priyanka and Pinki complete their respective distance at the same time. The total distance travelled by all of them on foot is 250 km. Find the respective ratio of the average speed of Priyanka and Pinki in this case?
If the total distance travelled by all of them on foot is 300 km. Find the sum of the total distance travelled by all of them by car and by rickshaw? (approximately)
Each of the two girls Rinki and Munni starts their journey at 10: 30 AM but Munni take 1-hour rest in the middle of the journey but each of them reaches their respective distance at 00:30 AM on the next day. Find the ratio of the respective average speed of Rinki and Munni? (It is given that the average of the total distance travelled by Priyanka and Pinki together on foot is 125 km)
The sum of the total distance travelled by Priyanka and Pinki together on foot is 125 × 2 = 250 km
From the data table, the sum of the total distance travelled by Priyanka and Pinki together on foot = (20 + 30) % of the total distance travelled by all of them on foot
50% of the total distance travelled by all of them on foot = 250 km
the total distance travelled by all of them on foot
= 250 ×
100
= 500 km
50
the total distance travelled by Rinki on foot = 25% of 500 = 125 km = 22% of the total distance travelled by her 22% of the total distance = 125
Total distance = 125 ×
100
22
Total time taken by her = 14 hrs
Speed =
(125 × 100)
km/hr
(14 × 22)
the total distance travelled by Munni on foot = 25% of 500 = 125 km = 20% of the total distance travelled by her 20% of the total distance = 125
