Find the rates at which Ravi walks, drives and rides. It is given there are three towns A, B and C and Ravi travels the distances between A and C via B and returns to A by three different modes of travelling. It is also given that to walk a km, ride a km and drive a km he takes altogether half an hour.
(A) By walking from A to B, driving from B to C and riding from C to A, Ravi completes the journey in 151⁄2hours.
(B) By driving from Ato B, riding from B to C and walking from C to A, Ravi can complete the journey in 12 hours.
(C) On foot Ravi can complete the journey in 22 hours, on horse back in 8% hours and by driving in 11 hours.
D. Either (C) or (A) and (B) together are sufficient
Answer & Explanation
Answer : Option
From C: Rates of walking, driving, riding are proportional to 1/22, 1/11, 1/8 1/4 i,e 3,6,8 respectively. Thus he walks 3k km in an hour, drives 6k km in an hour, and rides 8k km in an hour. From A and C: Let the distances between AB, BC and CA be x, y and z. Then
x/3k + y/6k + z/8k = 15 1/2 ........(1)
From B and C:
x/6k + y/8k + z/3k = 12 ...........(2)
Again, from C :
x+y+z/3k = 22 ............(3)
With the help of (C) and the last part of the question. we get the information that
1/3k + 1/6k + 1/8k = 1/2 ∴ k = 5/4
Now we have three unknowns and three equations. Hence we can get the required rates easily.
Two trains X and Y are moving in the opposite directions on parallel tracks. What time will the two trains require to cross each other completely ?

(B) The speeds of the trains X and Y are 120 km/hr and 160 km/hr respectively.
(C) The first train crosses a telegraph pole in 3 seconds while the second train crosses the telegraph pole in 6 seconds.
