# Trains Questions and Answers : Quantitative Aptitude

1. 21.   A 240m long train is running at 90kmph. If it crossed the platform in 30sec, then find the length of the

platform?

 A.) 490m B.) 500m C.) 510m D.) 550m

L = S*T

L=90*5/18*30

L=750m

Length of Platform= Length-Length of the Train = 750 – 240 = 510m

2. 22.   Two trains running in opposite directions at 40kmph and 50kmph, cross each other in 30sec. the

length of one train is 250m, then find the length of other one?

 A.) 440m B.) 490m C.) 500m D.) 510m

L = S*T

L = 90*5/18*30

L = 750m

```Length of second train= total length - Length of first train
= 750 - 250 = 500m
```

3. 23.   Two trains are running at 60 Kmph and 42 Kmph respectively, in same direction. Fast train completely

passes a man sitting in the slower train in 30sec. what is the length of the faster train?

 A.) 100m B.) 125m C.) 150m D.) 175m

L = S * T

L = 18 * 5/18 * 30

(in same direction Speed = first train - second train)

= 150m

4. 24.   A train crosses a platform of 120m in 15sec, same train crosses another platform of length 180m in

18sec. then find the length of the train?

 A.) 175m B.) 180m C.) 185m D.) 170m

Length of the train be ‘X’

X + 120/15 = X + 180/18

6X + 720 = 5X + 900

X = 180m

5. 25.   A train crosses a platform of 150m in 15sec, same train crosses another platform of length 250m in

20sec. then find the length of the train?

 A.) 150m B.) 165m C.) 155m D.) 160m

Length of the train be ‘X’

X + 150/15 = X + 250/20

4X + 600 = 3X + 750

X = 150m
