# What is the Total Journey of A Man? If

A man performs 4/7th of the total journey by train, 5/21th by car and the remaining 8 km on foot. His total journey is:

- 42 km
- 21 km
- 30 km
- None of these

**Answer: (4) None of these**

**Explanation:-**

Let the total journey be X km.

A man covered journey by train = X x 4/7

= 4 X/7

And man covered journey by car = X x 5/12

Remaining journey = 8 km

Then.

X – (4 X/7 + 5 X/12) = 8

X – (32 X + 35 X)/84 = 8

84 X – 67 X = 8 x 84

17 X = 672

X = 672/72

X = 39.52 km

Then, the total journey is 39.52 km.

Hence, the answer is (4) None of these.
