Karan and Arjun run a 100 metre race, where Karan beats Arjun by 10 metres. To do a favour to Arjun, Karan starts 10 metres behind the starting line in a second 100 metre race. They both run at their earlier speeds. Which of the following is true in connection with the second race?
Explanation:
In the first race when Karan runs 100 m, Arjun runs 90 m.
∴ Ratio of Karan’s and Arjun’s speed = 10 : 9
In the second race, when Karan runs 110 m, Arjun runs 110×910 = 99 m
∴ Karan beats Arjun by 1 m.
Hence, option (d).
