Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. 2 minutes, 15 seconds.
Ram and Ramesh run two kilometres and Ram wins by 40 seconds and,
When Ramesh and Naresh run the same distance, Ramesh wins by 25 seconds
then, Ram won by Naresh by = 40 + 25 = 65 sec
Ram and Naresh run two kilometres and Ram wins by 650 metres
Naresh travel 650 m in 65 sec
1 m in 65/650 or 1/10 sec
Distance travelled by Naresh = 2 km = 2000 m
Time taken = 1/10 × 2000 = 200 sec
Time taken by Naresh is 65 sec more than Ram = 200 - 65 = 135 sec or 2 min 15 sec
