A man covers $\frac{5}{12}$ of a total journey by train, $\frac{7}{18}$ of the journey by bus and the remaining 7 km on foot. His total journey (in km) is:
Answer & explanation
Correct answer: option 1
Solution,
\(\frac{5}{12}\)x + \(\frac{7}{18}\)x = \(\frac{29}{36}\)x,
⇒ x - \(\frac{29}{36}\)x = 7km,
⇒ \(\frac{7}{36}\)x = 7,
⇒ x = 36,
Therefore total distance traveled is 36 Km.
