Question : A man cycles at the speed of 8 km/h and reaches the office at 11 am and when he cycles at the speed of 12 km/h, he reaches the office at 9 am. At what speed should he cycle so that he reaches his office at 10 am?
Option 1: 9.6 km/h
Option 2: 10 km/h
Option 3: 11.2 km/h
Option 4: cannot be determined
Correct Answer: 9.6 km/h
Solution : Given: First speed = 8 km/h and second speed = 12 km/h The starting time will be the same in both conditions. Distance travelled by first speed in 2 hours, We know that, Distance = Speed $\times$ Time ⇒ Distance = 8 $\times$ 2
Question : Two friends, P and Q, start running around a circular track from the same point. They run in the same direction. P runs at 6 m/sec and Q runs at b m/sec. If they cross each other at exactly two points on the circular track and b is a natural number less than 6, how many values can b take?

Option 2: 1
Option 3: 4
Option 4: 3
Correct Answer: 1
Solution : If the ratio of their speeds is $V_1:V_2$, the distinct meeting points will be $V_1-V_2$, with both are running in the same direction. Try different values of $b$ from 1 to 5 and check which satisfies $V_1-V_2 = 2$ $\frac{V_1}{V_2}=\frac{6}{b}$; number of points is 2
