Mathematics Question on Problem on Trains
Raghu travelled 1200 km by air which formed 32th of his trip. One - third of the whole trip he travelled by car and the rest of the journey he did by train. The distance travelled by train is
A
1600 km
B
800 km
C
1800 km
D
480 km
Answer
800 km
Explanation
Solution
Let, the whole distance travelled be 'x',
Raghu travelled 1200 km by air which formed 52th of this trip,
52th of x =1200
x = 3000 km
One - third of the whole trip he travelled by car,
31×3000=1000 km
The rest of the journey he did by train,
∴The distance travelled by train = 3000 - (1200 + 1000)
⇒ 800 km
Hence, option B is the correct answer.The correct option is (B): 800 km
