Question

a man Travels 3 by 5 of his journey by train one by 8 by bus and one by for by taxi and the remaining 8 km on foot and his total distance travelled

Answer 1

Let The Total Distance Be "x"Km.

Now.
According to the question...

$\frac{3x}{5} + \frac{x}{8} + \frac{x}{4} + 8 = x \\ > > \frac{3x}{5} + \frac{3x}{8} = x - 8 \\ > > \frac{39x}{40} = x - 8 \\ > > 39x = 40x - 320 \\ > > 320 = 40x - 39x \\ > > 320 = x$
So the Total Distance Travelled=320Km.

Hope it Helps...
