| A and B run a 5 km race on a round course of 400 m. If their speeds are in the ratio 5 : 4, then number of times, the winner passes the other, is |
A) 1
B) 2
C) 3
D) 5
Correct Answer: C
Solution :
| A and B covers the distances in the ratio of 5: 4. |
| \[\therefore \] When A covers the distance of \[5\times 400=2000m\] |
| Then B will cover the distance of \[4\times 400=1600\] |
| That is A will meet B once in covering 1600 m. |
| \[\therefore \] A will meet B 3 times in covering 4800 m. |
| Thus, A will pass B 3 times in 5 km race. |
