From (i) and (ii), if H sits at place no. 5, then D sits at place 1. Also people sitting adjacent to him at place 2 and 8 are students and learn maths. Since H does not study computers and maths, therefore he learns accounts. From (iii), it is clear that the person sitting at place 4 is a student and studies computers. The one sitting at place 3 is a teacher who teaches computers. Also, person sitting at place 6 and 7 will be teacher and student respectively studying accounts.
From (iv), A will sit at place no 7. From (v), it is clear that since F is not a student, F sits at either place 3 or 6. C sits immediate left of F, hence, F sits at place no. 3 and C sits at place no. 2.
From (vi), E sits at place no. 6. Since B does not study maths, he studies computers and sits at place no. 4. G sits at place no. 8.
Now we can answer all the questions with the help of the above arrangement:
A Swimmer Walks 45km along the river's flow in 3 hours 45 minutes and walks 15km against the flow in 2 hours 30min. Find the speed of the boat in Still ...
Speed of boat is 20 km/hr. Speed of the stream is 20% less than speed of boat. Then find time taken by boat to go 90 km downstream.
A boat is navigating a river with a current speed of 2 km/h. It takes the boat 75 minutes longer to cover a distance of 56 km upstream than it does to c...
A man row a boat 1 km in 5 min, along the stream and 6 km in 1hrs against the stream, The speed of the stream will be
A man can row 32 km/hr in still water. It takes him thrice as long to row up as to row down the river. Find the rate of the current.
The downstream speed of a boat is 6 km/hr more than its upstream speed and the ratio of the speed of the boat in still water to the speed of the stream ...
If the sum of upstream and downstream speed is 48 km/hr and the speed of the current is 4 km/hr. Then find time taken to cover 84 km in downward?
The speed of the stream is 14 km/h. Boat ‘A’ covers 130 km distance against the stream in 5 hours and boat ‘B’ covers 100 km distance against th...
A boat goes 60 km in upstream in 5 hours and takes 3 hours to complete a distance of 12 km in downstream. Find the speed of boat in still water.
A man can row at 2 kmph in still water. If the velocity of current is 1 kmph and it takes him 4 hour to row to a place and come back, how far is the place?
