उत्तर
Distance covered by car = 60 km
Distance covered by train = 240 km
∴ Total journey = 60 + 240 = 300 km
Let x% of total journey is travelled by car.
Then, x% of 300 = 60
⇒ `x/100 xx 300 = 60`
⇒ `x = (60 xx 100)/300`
⇒ x = 20%
Let y% of total journey is travelled by train.
Then, y% of 300 = 240
⇒ `y/100 xx 300 = 240`
⇒ `y = (240 xx 100)/300`
⇒ y = 80%
Hence, 20% distance is travelled by car and 80% distance Is travelled by train.
