Question

A man travelled 60 km by car and 240 km by train. Find what per cent of total journey did he travel by car and what per cent by train?

Answer 1

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.
