You should use the given data and your knowledge of Mathematics to choose between the possible answers. Quantity A: A boat goes 328 km upstream in 8 hours and a distance of 245 km downstream in 7 hours. The speed of the boat in still water is Quantity B: A man in the backseat of a car notices that he can count 7 bus stops in one minute.

Given below are two quantities named A & 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 boat goes 328 km upstream in 8 hours and a distance of 245 km downstream in 7 hours. The speed of the boat in still water is Quantity B: A man in the backseat of a car notices that he can count 7 bus stops in one minute. If they are known to be 100 m apart, at what speed is the car travelling? Correct Answer Quantity A > Quantity B

Quantity A:

Speed of the boat upstream = 328/8 = 41 kmph

Speed of the boat downstream = 245/7 = 35 kmph

We know that,

Speed of the boat in still water = (Upstream speed + Downstream speed)/2

⇒ Speed of the boat in still water = (41 + 35)/2 = 38 kmph

∴ Speed of the boat in still water = 38 kmph

Quantity B:

Distance travelled by the car = (7 – 1) × 100 = 6 × 100 = 600 m

(We have taken 6(i.e., 7 - 1 = 6) here, ∵ the car starts at the first bus stop and distance is calculated between two points, so the first bus stop is the reference point from which the distance is to be calculated.)

∴ Speed of the car = 600 m/min = 600 × (60/1000) = 36 km/hr

∴ Quantity A > Quantity B

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.
