We have, U sits opposite to the one who sits second to the left of O. Only two persons sit between K and O. K sits to the left of O. From the above condition, there are three possibilities. Again we have, The number of persons sit to the left of U is the same as the number of persons sits to the right of Y. W sits second to the right of Y. J sits immediate left of M, none of them sits at end of the row. Again we have, L sits opposite to the one who sits second to the left of Z. X and Y are not immediate neighbours. From the above condition, case2 and case3 get eliminated. Case1 shows the final arrangement.

...The time taken by a boat to travel 'd' kilometers downstream is 8 hours, while the time taken to travel (d - 60) kilometers upstr...
A man can row at 4 kmph in still water. If the velocity of current is 3 kmph and it takes him 8 hour to row to a place and come back, how far is the place?
A boat running downstream covers a distance of 45 km in 9 hrs and covering the same distance upstream in 15 hrs. What is the speed of a boat in still wa...
A boat can travel 38 km downstream in 57 min. The ratio of the speed of the boat in still water to the speed of the stream is 3: 2. How much time will t...

The speed of a boat in still water is 16 km/hr. If the boat covers 180 km in upstream in 12 hours, then find the time taken by the boat to travel 170 km...
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 goes 200 km downstream in 50 hours, and 90 km upstream in 30 hours. The speed of the stream is
