Question
11 out of 35
 

Karan and Arjun run a 100 m race, where Karan beats Arjun by10 m. To do a favour to Arjun, Karan starts 10 m behind the starting line in a second 100 m race. They both run at their earlier speeds. Which of the following is true in connection with the second
race?



A Karan and Arjun reach the finishing line simultaneously

B Arjun beats Karan by 1 m

C Arjun beats Karan by 2 m

D Karan beats Arjun by 1 m

Ans. D

Situation (I):

In whatever time Karan covers a distance of 100 m, Arjun covers 90 m in the same time.

Situation (II):

Now Karan is 10 m behind the starting point. Once again to cover 100 m from this new point Karan will be taking the same time as before. In this time Ariun will cover 90 metres only. This means that now both of them will be at the same point, which will be 10 metres away from the finish point. Since both of them are required to cover the same distance of 10 m now and Karan has a higher speed, he will beat Ariun. No need for calculations as option (d) is the only such option.
