Min-Max Game
A and B play the following min-max game. Given the expressionN = 12 + X*(Y - Z)where X, Y and Z are variables representing single digits (0 to 9), "A" would like to maximize N while "B" would like to minimize it. Towards this end, "A" chooses a single digit number and "B" substitutes this for a variable of her choice (X, Y or Z). "A" then chooses the next value and "B", the variable to substitute the...

Points on Plane
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). Find the maximum value of n1(P) over all configurations P of 10 points in the plane.

Numerical Ability
A super fast bus of KSRTC starting from 'Trivandrum' and reaches 'Attingal' in 45 minutes with an average speed of 40 km/hr. If the speed is increased by 10 km/hr how much time it will take to cover the same distance?(a) 34 minutes (b) 36 minutes (c) 38 minutes (d) 40 minutes
dinesh_madhu623

Answer is 36 mins We can approach the problem as followsFirst we have to find the distance we can do so byspeed = 40Time = 45 minshence dt = speed * ttdt = 2 * (15)dt = 30Now the speed can be increased by 10 now the speed is 50tt = dt/speedtt = (30/50) * 60tt = 0.6 * 60tt = 36.0

B) 36 mind=s*ts=40 km/hr=40/60km/mint=45mind=(4/6)*45=30kmnow increased speed= 50 km/hr=50/60 km/mind=30 kmt=d/s = 36 min

It fills at a rate of 2 (i.e) 10,20,40.... 1/16 is filled in 17hr. then it fills as 1/8,1/4,1/2,1.. Hence 17+1+1+1+1=21
