The following question consists of three statements. You have to study the question and the statements, and decide which of the statements is/are necessary to answer the question. What is the speed of the current? I. Speed of the boat is 8 km/hr in still water II. The boat runs at a speed of 11 km/hr downstream III. The difference between the speeds of the boat while travelling in still water and down-stream is 3 km/hr Correct Answer Either I and II together or only III

Calculation:

(i) Speed of the boat in still water = 8 km/hr

(ii) Speed of boat in downstream = 11 km/hr

⇒ Speed of the current = Speed of boat in downstream – Speed of boat in still water

⇒ 11 – 8 = 3 km/hr

(iii) The difference between the speeds of the boat while travelling in still water and downstream = 3 km/hr

∴ Either I and II together or only III

Given below are two quantities named A and B. Based on the information, you have to determine the relationship between two quantities. You should use the given data and your knowledge of Mathematics to choose between the possible answers. Quantity A∶ Total time taken by a boat travelling from A to B and B to A, is 1 hr 4 min. Speed of the boat in still water is 16 km/hr and speed of the current is 4 km/hr. what is distance between A to B ? Quantity B∶ Total time taken by a boat travelling from A to B and B to A, is 1 hr 10 min. speed of the boat in still water is 18 km/hr and speed of the current is 2 km/hr. what is distance between A to B?
In the following question, three statements are given. You have to find which is/are necessary and sufficient to answer the following question. Find the speed of the boat in still water. Statement I: The boat goes twice the distance downstream in the same time, as it goes upstream. Statement II: Speed of the boat in still water is three times the speed of the current. Statement III: The boat goes 840 meters in 1 hour 10 minutes downstream.
Study the following questions carefully and answer accordingly. Quantity - I) If the time taken by a boat to cover the same distance in upstream is 2 hours more than downstream. The downstream speed of the boat and the speed of current is 16 kmph and 4 kmph then find the total distance travelled by the boat? Quantity - II) If the time taken by the boat in upstream and in downstream is 16 hours and 10 hours to cover the same distance. Then find the speed of boat in still water is how much percent of the speed of stream? Quantity – III) If the length of rectangle is twice of its breadth and 3 times more than the side of square and the difference between the side of square and length of rectangle is 15 cm then find the area of rectangle ?

III) The boat can cover the downstream distance of 33.75 km in 2 hrs. 15 min.
The following question has three statements. Study the question and the statements and decide which of the statement(s) is/are necessary to answer the question. What is the speed of boat in still water? I. The boat can cover 25 km downstream distance in 5 hours. II. Speed of the stream is two-third of the speed of boat in still water.

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.
Questions below followed by two quantities. Find the relation between them. The table shows the distance travelled by five different boats upstream, the speed of the boat in still water and the time taken by them to cover the upstream distance. Boats Upstream distance Speed of boat Time taken  A  240 km  15 km/hr  20 hr  B  150 km  10 km/hr  25 hr  C  350 km  20 km/hr  50 hr  D  96 km  8 km/hr  16 hr  E  126 km  26 km/hr  9 hr   Quantity I: Boat B travel 238 km distance downstream in certain time. How much downstream distance boat D will cover at the same time? Quantity II: Boat E travel 722 km distance downstream in certain time. How much downstream distance boat A will cover at the same time?
In the following question, two statements are numbered as A and B. On solving these statements we get quantities A and B respectively. Solve for the both quantities and chose the correct option. Quantity A: The ratio of speed of boat to speed of stream is 2 : 1, If the boat travels 162 km and come back to starting point in 36 hour. What is the difference between the time taken by the boat to go upstream and the time taken by the boat to go downstream? Quantity B: The speed of the stream is 6 km/hr and the distance travelled by the boat is 60 km. If the boat covered half distance upstream with usual speed and other half with double its speed, then it takes 7.5 hours less time than usual time to go upstream. Find the total time taken by the boat to go upstream and downstream?
