The Correct Option is D
Solution and Explanation
Considering that the trip took place across a total of 26862 kilometers and lasted for 8 hours.
The kilometers traveled up to immediately before the trip is 26862 - 8s, which should likewise be a palindrome, if the average speed of the vehicle during the journey is's'.
Among the choices the reading will be \(26862 - 110\times8 = 25982\) (Not a palindrome)
If s = 110 the reading will be \(26862 - 100\times8 = 26062\)
If s = 100 it's a palindrome.
=> s = 100 is the right choice.
The correct answer is 100.

Statement I: Ravi walks from his house at a speed of 5 km per hour and reaches the college 10 minutes late. If he increases the speed by 1 km per hour next day, he reaches the college 4 minutes earlier than the scheduled time. If the college is P km far from his house, then P = 7.5 km.
Statement II: Amit runs \(2\frac{1}{3}\) times as fast as Babita. If Amit gives Babita a start of 80 meters, then the winning post must be 140 meters far so that Amit and Babita might reach it at the same time.
