A man can reach a certain place in 40 hours . If he reduces his speed by 1/15th, he goes 5 km less in that time . Find the total distance covered by him.

A man can reach a certain place in 40 hours . If he reduces his speed by 1/15th, he goes 5 km less in that time . Find the total distance covered by him. Correct Answer 75 km .

Correct Option: DLet Distance = D km, Speed = S km/h Time = Distance Speed 40 = Distance .... (1) Speed After reducing speed, Distance = Distance – 5 km, Speed = S × 14 km/h 15 Time = Distance Speed 40 = (Distance – 5) .... (2) Speed × 14 15 After solving equation 1 and 2 Distance = (Distance – 5) Speed Speed × 14 15 14 Distance = 15 (Distance – 5)14 Distance = 15 Distance – 75Distance = 75 km.Hence, option D is correct.

Each of the question below consists of a question and three statements number I, II and III given below it. You have to decide whether the data provided in the statement are sufficient to answer the question. 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.
Given below are two quantities named A and B. Based on the given information, you have to determine the relation between the two quantities. You should use the given data and your knowledge of Mathematics to choose between the possible answers. Quantity A: A person who travels a certain distance to his office by his car.If he increases his speed by 8 km/hr, he takes 2 hours less time but if he drives 8 km/hr slower, he takes 4 hours more time. Find the distance of office from home. Quantity B: A person who travels a certain distance to his office by his car. If he increases his speed by 10 km/hr, he takes 1 hour less time but if he further increases his speed by 5 km/hr, he takes further 20 minutes lesser time. Find the distance of office from home.

Paddy transplantation in Punjab is a very hard labor-intensive back-breaking job. In the transplant season, teams of special people swarm the entire rural landscape employed by the farmers and can be seen laboring away in the fields under the hot sweltering sun. Farmer Jagtar Singh has a full-time help at his sprawling farm who goes by the name of Hari, and who hails from Allahabad, UP. During the paddy transplant season, it is up to Hari to rope in his brothers, sons, and cousins from his native village to complete the task well in time. All his people are skillful and masters of the trade and equally efficient at their jobs. So, this past season, this is how the work went. Hari started the work and after 't' hours was joined in by his brother Jaggi. After another 't' hours, Neelu, their cousin, also jumped into the fray. So, after every 't' hours, 1 person kept on joining the team of already working men, and this process kept on continuing till the completion of the work. The last person worked for 't' hours. In the last season, the very same men had completed the same work working 2 shifts of 12 hours all of them working simultaneously owing to some peculiar weather conditions and time constraints. Jagtar Singh is a fair and just paymaster which is why he faces no labor shortage at this crucial time and which is why the whole 'Hari clan' are more than happy to work for him and are at his beck and call. He pays each of them individually proportional to the work done by them. This time around, Hari received 11 times as much as Surinder, his eldest son, who was the last person to join in. In how much time was the work completed?
A boatman wants to cross a river which distance is 80 km. In the starting boatman goes to 20 km and then turn 90 degree anti-clock wise and goes 60 km in upstream after that he turn 90 degree clock wise and goes 40 km. After that he turn 90 degree clock wise and goes 60 km. In the end he turn 90 degree anti-clock wise and goes 20 km and reach his destination. The speed of boatman is 22 km/hr and speed of stream is 4 km/hr. Find the time to cover total distance?
Ramesh covered 40% of a distance with original speed and remaining distance he covered with speed 10 km/h less than the original speed.
