Q: A train runs through cities A, B, C, D, E, F, G and H. The line graph indicates the time schedule of the train including times of arrival and departure. 1. The total stoppage time at the cities in the first half and second half of the total distance is in the ratio. 1. 1 : 3             2. 3 : 1             3. 2 : 1             4. 1 : 2 2. Between how many pairs of consecutive stations does the speed run below the overall average speed of the entire trip? 1. 2                     2. 1                    3. 3                     4. 4 3. If the train stops at each city for 50% more time than what it is at present, then at what time will it arrive at city H after departing from city A as per schedule ? 1. 20.16             2. 19.02             3. 18.51             4. 18.59 4. The overall average speed of the entire trip excluding stoppage time is nearly : 1. 75 km/h        2. 81 km/h        3. 46 km/h        4. 65 km/hr 5. What percent of time of the entire trip was actually spent travelling between the cities ? 1. 91.8%             2. 7.6%             3. 76%               4. 24%

Answer :
Explanation :

1. Answer : 4 Explanation : Required ratio = 10+2+510+15+10=1735≈12=1:2    2. Answer : 1 Explanation :  A to B Speed =140×35  = 84   B to C Speed = 91×34 = 68.25  C to D Speed = 149×60103 = 86.796   D to E Speed = 88×34 = 66   E to F Speed =  106×45= 84.8   F to G Speed = 1762 = 88   G to h Speed =  110×45= 88   Average speed of entire trip = 84+68.25+86.796+66+84.8+88+887 =80.83    3. Answer : 3  Explanation :  Total half time = 10 + 2 + 5 + 10 + 15 + 10 = 52  Total half time, if the train stops at each city for 50% more=52×150100=78  Train will arrive at city H after departing from city A = 18.25 + (78 - 52 )=18.25 + 26=18.51   4. Answer : 2   Explanation : Average speed = 84+68.25+86.796+66+84.8+88+887=80.83=81 km/hr   5. Answer : 1  Explanation :  Required percentage of time = 1.40+1.20+1.43+1.20+1.15+2+1.1518.25-7×100= 10.2311.25×100 = 91.8 %
