Question 6 : |
Starting from 5 p.m., 8 trains – A to H – left CST station at intervals of 5 minutes each. The speed of each train is a distinct natural number. Ravi, a train-cum-math aficionado, also knew that: 1. The speed of H is 4 km/min and the speed of D is the average of the speeds of H and B. 2. The speed of B and C is in the ratio 1 : 3. 3. F, at 8 km/min, is the fastest of the trains. 4. A is faster than G, and always beats G by 2 kms every minute. 5. E was the third to leave. 6. The ratio of the running time of H and G is 6 : 7 and that of D and A is 6 : 5 7. The difference between the running times of E and B is the same as that between A and F. 8. F travels the maximum distance. Can you help Ravi create a unique train timetable and help him find the distance each train had travelled at 7 p.m. on the same day. |

Question 3 : |
Ronak (facing north) wants to drive from his house at point A to his friend’s house at B. He travels 20 km to the right and takes a left turn. Now, while driving on this road, he misses the right turn that directly takes him to his friend’s house. So, he drives 60 km on this road and takes the next available right turn. He now drives for 40 km, takes a right turn, drives 30 km, takes another right turn and drives 20 km to finally reach his friend’s house. If Ronak’s car gives a mileage of 14 kmpl and 1 litre of petrol costs Rs. 80, how much money has Ronak wasted? Assume that there is no other road that connects points A and B. |
A : Rs. 571.4 |
B : Rs. 971.4 |
C : Rs. 685.7 |
D : None of the above |
