Ravi has to go from Hyderabad to Delhi. The distance between Hyderabad and Delhi is 1,200 kms. He decides to travel 25% of the distance on foot, 30% of the distance by bus, 15% of the distance by train and the remaining distance by an airplane. What is the distance travelled by Ravi by an Airplane? Correct Answer 360 km

GIVEN :

Total Distance to be covered = 1200 kms.

Distance travelled on foot = 25%

Distance travelled by bus = 30%

Distance travelled by train = 15%

CONCEPT :

Remaining Distance travelled by airplane  = Total Distance - (Distance travelled on foot + Distance travelled by bus + Distance travelled by train)

CALCULATION :

Let the Total distance be 100%.

According to question,

100% = 1200 Kms

Remaining Distance travelled by airplane  = Total Distance - (Distance travelled on foot + Distance travelled by bus + Distance travelled by train)

⇒ 100% - (25% + 30% + 15%)

⇒ 100% - 70%

⇒ 30%

Remaining Distance = 30%

Now,

100% = 1200 Kms

∴ 30% = 1200 × (30/100) = 360

⇒ Remaining Distance = 360 Kms

∴ The distance travelled by Ravi by an Airplane is 360 Km.

If the bus is travelling from Surat to Ahmadabad and a car is travelling from Ahmadabad to Surat, then what is the distance between Surat and Ahmadabad? I. The speed of a car is 40% less than the speed of bus. Bus started at 9 am and car started at 10 am and they meet at 3 pm of the same day. II. After travelling for 1 hour, because of traffic average speed of bus is decreased by 20% and covers distance between Surat to Ahmadabad in 11 hours. Original speed of car is 20% less than original speed of bus and before crossing bus it covered 200 km if starts 1 hour later than bus. After crossing car, bus covers remaining distance in 5 hours. III. Speed of bus is 10 km/hr more than the speed of car and before crossing car ratio of distances covered bus and car in same time was 5 : 4. Time taken by car to cover the distance between Ahmadabad and Surat is 2 hours 15 minutes more than time taken by bus to cover the same distance.
In a survey, people who travel by car, train or bus; 60% travel by only one medium, out of which ratio of those travel by only car, only train and only bus is 4 : 5 : 3. If 10% of total travel by both train and bus but not car, then people travel by train but not car is what percent more than the people travel by bus but not by car?

There is only one rail track between stations A and B on a railway line. One hour after the northbound superfast train N leaves station A for station B, the southbound passenger train S reaches station A from station B. The speed of superfast train is twice that of express train E, while the speed of passenger train S is half of that of train E. On some one day train N leaves from station A to station B 20 minutes late than its usual schedule. Both Train N and Train S have increased their speed to maintain the schedule as per the table. If the superfast train doubles its speed, then what should be the ratio (approximately) of the speed of the passenger train to the speed of the superfast train so that the passenger train reaches the station on that day at the exact scheduled time.
