Answer» Let the journey covered by train, bus and car = ‘4a’, ‘3a’ and ‘2a’ respectively. Let fare of train, bus & car = ‘b’, ‘2b’ and ‘4b’ per km. Then, fare paid for train, bus & car = 4ab, 6ab, 8ab respectively. ∴ Total fare = 4ab + 6ab + 8ab = 18ab Given that, ⇒ 18ab = 720 Or, ab = 40 ∴ Fare spent on train = 4ab = 4 × 40 = Rs. 160.

Answer»

Let the journey covered by train, bus and car = ‘4a’, ‘3a’ and ‘2a’ respectively.

Let fare of train, bus & car = ‘b’, ‘2b’ and ‘4b’ per km.

Then, fare paid for train, bus & car = 4ab, 6ab, 8ab respectively.

∴ Total fare = 4ab + 6ab + 8ab = 18ab

Given that,

⇒ 18ab = 720

Or, ab = 40

∴ Fare spent on train = 4ab

= 4 × 40 = Rs. 160.
