RRB NTPC · Question 67
Ram travels 4/9th of the total journey by bus, 5/18th by rail, and the remaining 10 km on foot. Find the distance of the total journey. A. 42 km B. 90 km C. 36 km D. 18 km
Show answer & explanation
Answer: (D) C
Explanation
Bus and rail together cover 4/9 + 5/18 = 8/18 + 5/18 = 13/18 of the journey, leaving 5/18 on foot. So 5/18 of the total = 10 km, and the total = 10 × 18/5 = 36 km.
