Question
In each question below are given three statements
followed by three conclusions numbered I, II and III. You have to take the two given statements to be true even if they seem to be at variance with commonly known facts and then decide which of the given conclusions logically follows from the three given statements, disregarding commonly known facts. Â Statements:Â Â Â Â Â Â Â Â Â Â Â Â Â Â All apples are bananas. All pears are bananas. All bananas are papayas. Conclusions:Â Â Â Â Â Â Â Â Â Â Â I. All apples are papayas. II. All pears are papayas. III. Some papayas are apples.Solution
All apples are bananas. (A) + All bananas are papayas(A) = All apples are papayas(A). Hence, conclusion I will follow. All pears are bananas (A) + All bananas are papayas(A) = All pears are papayas. Hence, conclusion II will also follow. All apples are papayas(A) ⇒ conversion ⇒ Some papayas are apple (I). Hence, conclusion III will also follow.
- Upstream speed of a boat is 22 km/h. Time taken by boat to cover 144 km downstream is 1 hour more than that taken by it to cover 77 km upstream. Speed of a...
A boat takes 4 hours to travel 48 km downstream and 6 hours to travel the same distance upstream. What is the speed of the boat in still water?
When travelling downstream, a boat takes 5 hours to travel 300 km. If the speed of the stream is (2/5)th of downstream speed of the boat, the...
The downstream speed of a boat is 8 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 ...
A man takes 10 hours to row 21 km upstream from point A to point B and back to A by boat. If he takes the same time to row 7 km downstream as upstream. ...
The duration it takes for boat 'P' to cover 160 km downstream is equal to the duration it takes to cover 120 km upstream. If the ratio of the speed of b...
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?
Speed of current is equal to 15% of speed of boat in still water. If the boat takes 3 hours to cover 120 km in still water, then find the time taken by ...
Speed of a boat in still water is three times the speed of the boat in upstream. If the boat takes 10 minutes to cover 28 km in downstream, then find th...
