Let total journey be ‘x’ km.
A man performs 2/15 of the total journey by train. 2/20 by bus and the remaining 10 km on foot.
∴2/15x+2/20x+10=x
⇒x−2/15x−2/20x=10
⇒(60x−8x−6x)/60 = 10
⇒46x/60=10
x = 13.04 km
(Hope It Helps You)

Let the total journey of man be x km.
Then A/Q,
2/15 *x + 9/20*x + 10 = x
8x + 27x +600 / 60 = x
35x + 600 / 60 = x
5[7x + 120] / 60 = x
7x + 120/ 12 = x
7x + 120 = 12x
12x - 7x = 120
5x = 120
x = 24
Then A/Q,
2/15 *x + 9/20*x + 10 = x
8x + 27x +600 / 60 = x
35x + 600 / 60 = x
5[7x + 120] / 60 = x
7x + 120/ 12 = x
7x + 120 = 12x
12x - 7x = 120
5x = 120
x = 24
Put this equation equal to x and soove a bit you are much intelligent to do that much and you will get the desired answer.
