The pacelength P is the distance between the rear of two consecutive footprints. For men,

the formula, n/P = 144 gives an approximate relationship between n and P where, n =

number of steps per minute and P = pacelength in meters. Bernard knows his pacelength

is 164cm. The formula applies to Bernard's walking. Calculate Bernard's walking speed

in kmph.

There are two water tanks A and B, A is much smaller than B. While water fills at the

rate of one litre every hour in A, it gets filled up like 10, 20, 40, 80, 160 .. in tank B.

(At the end of first hour, B has 10 litres, second hour it has 20, and so on). If 1/32 of B's

volume is filled after 3 hours, what is the total duration required to fill it completely?

Given a collection of points P in the plane, a 1-set is a point in P that can be separated

from the rest by a line; i.e. the point lies on one side of the line while the others lie on the

other side. The number of 1-sets of P is denoted by n1(P). The maximum value of n1(P)

over all configurations P of 10 points in the plane is

Ferrari S.p.A. is an Italian sports car manufacturer based in Maranello, Italy. Founded

by Enzo Ferrari in 1928 as Scuderia Ferrari, the company sponsored drivers and

manufactured race cars before moving into production of street-legal vehicles in 1947

as Ferrari S.p.A.. Throughout its history, the company has been noted for its continued

participation in racing, especially in Formula One, where it has enjoyed great success.

Rohit once bought a Ferrari. It could go 2 times as fast as Mohit's old Mercedes. If the

speed of Mohit's Mercedes is 32 km/hr and the distance travelled by the Ferrari is 952

km, find the total time taken in hours for Rohit to drive that distance.

A hare and a tortoise have a race along a circle of 100 yards diameter. The tortoise goes

in one direction and the hare in the other. The hare starts after the tortoise has covered

1/5 of its distance and that too leisurely. The hare and tortoise meet when the hare has

covered only 1/8 of the distance. By what factor should the hare increase its speed so as

to tie the race?

Planet fourfi resides in 4-dimensional space and thus the currency used by its residents

are 3-dimensional objects. The rupee notes are cubical in shape while their coins are

spherical. However the coin minting machinery lays out some stipulations on the size of

the coins.

The diameter of the coins should be at least 64mm and not exceed 512mm.

Given a coin, the diameter of the next larger coin is at least 50% greater.

The diameter of the coin must always be an integer.

You are asked to design a set of coins of different diameters with these requirements and

your goal is to design as many coins as possible. How many coins can you design?

Alok and Bhanu play the following min-max game. Given the expression

N = 12 + X*(Y - Z)

where X, Y and Z are variables representing single digits (0 to 9), Alok would like to

maximize N while Bhanu would like to minimize it. Towards this end, Alok chooses a

single digit number and Bhanu substitutes this for a variable of her choice (X, Y or Z).

Alok then chooses the next value and Bhanu, the variable to substitute the value. Finally

Alok proposes the value for the remaining variable. Assuming both play to their optimal

strategies, the value of N at the end of the game would be
