11. Every day a cyclist meets a train at a particular crossing. The road is straight before the crossing and both are traveling in the same direction. The cyclist travels with a speed of 10 Kmph. One day the cyclist comes late by 25 min. and meets the train 5km before the crossing. What is the speed of the train?

Explanation:

Speed of the train = 60km/hr.

Speed of Cyclist travel = 10km/hr.

It means, Cyclist travels 5km in 30minutes.

If Cyclist comes late by 25 min and meets the train 5km before the crossing means, it shows

Train can travel 5Kms in 5minutes.

So, speed of train is (5 km/5min) = 1 km/1min = 60km per hour.

16. Ahmed, Babu, Chitra, David, and Eesha each choose a large different numbers. Ahmed says, My number is not the largest and not the smallest. Babu says, My number is not the largest and not the smallest. Chitra says, My number is the largest. David says, My number is the smallest. Eesha says, My number is not the smallest. Exactly one of the five children is lying. The others are telling the truth. Who has the largest number?

Explanation:

Largest -> A B C D E
A F T/F T/F T/F T/F
B T/F F T/F T/F T/F
C F F T F F
D T/F T/F T/F F T/F
E T/F T/F T/F T/F T

From the above table, If we assume that A has the largest then A and C both are lying. Similarly if we find the truthfullness of the remaining people, it is clear that E has the largest and C lied. (Only one F in the last column)

18. A farmer has a rose garden. Every day he either plucks 7 or 6 or 24 or 23 roses. The rose plants are intelligent and when the farmer plucks these numbers of roses, the next day 37 or 36 or 9 or 18 new roses bloom in the garden respectively. On Monday, he counts 189 roses in the garden. He plucks the roses as per his plan on consecutive days and the new roses bloom as per intelligence of the plants mentioned above. After some days which of the following can be the number of roses in the garden?

Explanation:

If he plucks 23, then only 18 grows the next day. This means total roses get decreases by 5. So after n days assume the number of roses got decreased 185 where n = 37, then 4 roses left.

19. A circle has 29 points arranged in a clockwise manner numbered from 0 to 28. A bug moves clockwise around the circle according to the following rule. If it is at a point i on the circle, it moves clockwise in 1 second by ( 1 + r ) places, where r is the reminder ( possibly 0 ) when i is divided by 11. Thus if it is at position 5, it moves clockwise in one second by ( 1 + 5 ) places to point 11. Similarly if it is at position 28 it moves ( 1 + 6 ) or 7 places to point 6 in one second.
If it starts at point 28, at what point will it be after 9994 seconds?
