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
C

Explanation :

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 ?
(A) The ratio of the speeds of the trains is 3:4.
(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.

What is the annual income of Sudhanshu ?
(A) Sudhanshu earns Rs 1 lakh more than Amrendra in a year.
(B) The ratio of the annual income of Amrendra to that of Sanjeevis 1:3.
(C) Sanjeev's annual income is Rs 2 lakh more than Amrendra's.

D. All A, B and C even together are not sufficient

Answer & Explanation

Answer : Option
C

Explanation :

Sd - Am = 1 ... (i) Am = Sn = 1 : 3 ... (ii) Sn - Am = 2 ... (iii) f From (ii), Sn = 3Am Putting this in (iii), 3 Am - Am = 2 or Am = 1 Using this in (i), Sd = 1 + 1 = 2

Direction (Q. 6 - 10) : Each of the following questions consists of unmarked figures followed by five figures marked 1,2,3,4 and 5. Select a figure from the marked figures which will continue the series established by the unmarked figures.

The elements move 2, 2, 3, 3, 4 .... steps CW. The ACW, end element moves to the CW end in each step while a new element is added at CW end in alternate steps.

The arrow rotates by 45° ACW, 45° ACW, 90" CW, 45° ACW, ... in subsequent steps and moves two steps ACW The semilunar element moves diagonally. Fot others follow if 1 = 4, 2 = 5 then 3 = 6 rule.
