In an 800 m race, the ratio of the speeds of two contestants Ankur and Neha is 5 : 6. If Ankur has a head-start of 200 m, then Ankur will win by ______.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 80 m.
Let the speed of ankur be 5x and speed of Neha be 6x
Time taken by Ankur to complete the 600 m race as he had the head start,
⇒ Time = 600/5x = 120/x
Distance covered by Neha in the same time
⇒ 6x × 120/x = 720 m
Hence, Ankur win the race by a distance = 800 - 720 = 80 m
