A boat having a length of 3m and breadth 2m is floating on a lake. The boat sinks by one cm when a man gets on it. What is the mass of the man? Correct Answer 60kg

Fraction of volume above water surface = 1 – 0.90 = 0.10 Weight of man = Weight of water displaced by boat when the man gets in m×9.8=(3×2×0.01)×103×9.8 Hence, m = 60kg.

What is the distance covered by boat N upstream in 5 hours? Which of the following option is sufficient alone to find the answer? A) Boat M is travelling downstream with 20% more downstream speed of boat N. Speed of boat M in still water is 10% more than the speed of boat N in still water. B) Boat M and Boat N are travelling downstream with speed 33 km/hr and 40 km/hr respectively and speed of boat M is still water is 2 times the speed of stream. C) Speed of boat M in still water is 6 km/hr less then speed of boat N in still water and speed of stream is 10 km/hr. D) Speed of stream is ½ times the speed of boat N in still water and downstream speed of boat M is 44 km/hr. E) Speed of stream is 10 km/hr and ratio of upstream speed of boat M and boat N is 3 : 2 respectively.

Seven people A, B, C, D, E, F and G live on separate floors of a 7-floor building. Ground floor is numbered 1, first floor is numbered. 2 and so on until the topmost floor is numbered 7. Each one of these having a different cars-Cadillac, Ambassador, Fiat, Maruti, Mercedes, Bedford and Fargo but not necessarily in the same order. Only three people live above the floor on which A lives. Only one person lives between A and the one having a car Cadillac. F lives immediately below the one having a car Bedford. The one having a car Bedford lives on an even-numbered floor. Only three people live between the ones having a car Cadillac and Maruti. E lives immediately above C. E is not having a car Maruti. Only two people live between B and the one having a car Fargo. The one having a car Fargo lives below the floor on which B lives. The one having a car Fiat does not live immediately above D or immediately below B. D does not live immediately above or immediately below A. G does not have a car Ambassador. Question : How many people live between the floors on which D and the one having a car Bedford ?
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 ?
A middle school mathematics teacher asks his students to construct a rectangle with length 7 cm and breadth 4 cm. As the students completed the task, he further instructs them: (i) increase the length and breadth by 2 cm each and draw to see what figure you get (ii) decrease the length and breadth by 2 cm and draw to see what figure you get (iii) increase the length by 1 cm and decrease the breadth by 1 cm. Can you predict the type of figure without draving? Which principle of Zoltan Dienes theory of mathematics learning is he using in the above activity?
There are 5 people A, B, C, D, and E, having different cars Polo, Verna, Alto, Wagon R and Jeep. They were visiting on different day of the week to service center. No car gets it’s servicing done on Monday and Sunday. C is having Wagon R and visit service center on Friday. B don’t have Jeep. A visits service center on Tuesday. Polo gets it’s servicing done on Saturday. No person gets servicing done between A and D. B don’t have Polo car. Car alto gets serviced between Verna and Jeep. On which day Alto gets servicing and also determine who’s having Jeep?
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?
Ratio between speed of boat P and Q in still water is 8∶6 and speed of current is 8 km/hr. Boat Q starts from A in the downstream,2 hours earlier than Boat P and it is found that Boat P is 32 km ahead of boat Q after 16 hours of its start. If boat P starts from point B in down steam at the same time and distance between A and B is 216 km, then find at what time boat P and Q meet each other.
