According to the Question,
A man travels the distance by air = 50%
Travels the distance train = 35%
Travels the distance by bus = 10%
Travels the distance by taxi = 144 km

Step by Step Solution :

Let, total distance travelled by man is x
Therefore, By Air ,
= x × 30/100
= x/2 By Train,
= x × 35/100
= 7x/20 By Bus,
= x × 10/100
= x/10 Now remaining distance,
= x – x/2 – 7x/20 – x/10
= 20x – 10x – 7x – 2x/20
= x/20 Therefore,
x/20 = 144
= x = 2880 ∴ Air = 2880/2
= 1440 KM ∴ Train = 7 × 2880/20
= 1008 km ∴ Bus = 2880/10
= 288 Km

According to the Question,A man travels the distance by air = 50%

Travels the distance train = 35%

Travels the distance by bus = 10%

Travels the distance by taxi = 144 km

Step by Step Solution :Let,total distance travelled by man is xTherefore,

By Air ,= x × 30/100

= x/2

By Train,= x × 35/100

= 7x/20

By Bus,= x × 10/100

= x/10

Now remaining distance,= x – x/2 – 7x/20 – x/10

= 20x – 10x – 7x – 2x/20

= x/20

Therefore,x/20 = 144

= x = 2880

∴ Air= 2880/2= 1440 KM

∴ Train= 7 × 2880/20= 1008 km

∴ Bus= 2880/10= 288 Km
