Here in this blog , we are discussing about some basic aptitude questions in mathematics. Some of them are mentioned below .
1. Two trains of 100m long , moving in the opposite directions crosses each other in 8 seconds. One is moving twice as fast as the other. Then the speed of the faster train will be ?
Let the speed of the slower train be x m /sec
Then the speed of the faster train will be 2x m/ sec
Total distance = 100 + 100 = 200 m
Their relative speed = 3x m/sec
Total time taken = 8 seconds
- Speed = Distance / Time taken
- 3x = 200 / 8
- 3x = 25 => x = 25 /3 m/sec
2x = 50 /3 m/sec
= 50/3 * 18/5
- 2x = 60 kmph
Hence the speed of the faster train = 60 kmph
2.Find the ______ that accompany these cartoons
Answer : Captions
3.The passengers were afraid but the captain__________ that there was no danger. Answer : assured
4.The angle of the elevation of the sun , when the length of the shadow was 3 times the height of the tree is ?
Let the height of the tree = AB = x meters
- Length of the shadow = BC = 3x meters
Angle of elevation = AB / BC = 1 / 3 = tan 30o
Hence the angle of elevation = 30o
5.Rover weighs less than Fido.
Rover weighs more than Boomer.
Of the three dogs, Boomer weighs the least.
If the first two statements are true then the third statement is______
Answer : TRUE
Reason : i) Rover < Fido
ii) Rover > Boomer
iii) Boomer < Rover < Fido
