One grand father has 3 grand children two of the age difference is 3.Eldest child age is 3 times the youngest childs age and the eldest child age is two year more than the sum of other two children. Find what is the age of the elders child?
a)18 b)22 c)30 d)10

Solution

let the age of eldest child is E , that of elder child is M and that of youngest child is Y, then according to the given conditions
E = 3Y ....(1)
E = 2 + M + Y ....(2)
now third condition is somewhat complicated,
according to this condition 'two of the age difference is 3' so three cases will arise 1) E - M = 3, ......(3)
2) M - Y = 3, ......(4)
3) E - Y = 3, ......(5)
if we take first of the 3 conditions then on solving (1), (2) and (3) we will get E = 3, M = 0, Y = 1 which is wrong
now on solving (1), (2) and (4) we will get E = 15, M = 8, Y = 5
similarly on solving (1), (2) and (5) we will get E = 4.5, M = 1, Y = 1.5
only E = 15, M = 8, Y = 5 is correct so age of elder child is 8 years

A boy wants to make cuboids of dimension 5m, 6m and 7m from small cubes of .03 m3. Later he realized he can make same cuboids by making it hollow. Then it takes some cubes less. What is the number of the cubes to be removed?
a) 2000 b) 5000 c) 3000 d) 7000

Solution

volume of the small cube = 0.03 m^3
so side of this cube = cubic root of 0.03 m^3 = .312 m
so after removing the outermost layer the dimensions for the inner cuboid will be (5-2*0.312), (6-2*0.312), (7-2*0.312)
so total volume will be (4.376)*(5.376)*(6.376) = 150 m^3
so no of cubes will be 150/0.03 = 5000
so we can remove 5000 inner cubes

Let the length of the journey = x
so time taken = x/6 for first and x/4 for second journey
so avg. velocity = (x+x)/[(x/6)+(x/4)] = 4.8

(#M40000818) TCS QUESTION Keep an EYE

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 minimum value of n1(P) over all configurations P of 5 points in the plane in general position (.i.e
no three points in P lie on a line) is
(a) 3 (b) 5 (c) 2 (d)7

Solution

The meaning of this question is little complicated. In easy language the question should be:


There are some points in the plane. We have to make a separation between these points by forming a line in such a way that one point could be separate from the others. No 3 points are in a line. Maximum no of methods for plotting the line and minimum no of methods for plotting the line will be (arrangement of points is your choice)

Now Answer Is:

For Maximize: The number of methods, Points should be drawn in the circumference of the CIRCLE So answer would be the number of total point in the plane.

For minimize: The number of methods we should draw 3 points in a TRIANGLE and all other point inside this triangle in such a way that no 3 points could be in a line.

If it will be allowed to draw the points in a line then minimum possibilities will be 2 only, because if we take all points in a line then you can separate only the corner points from the others.

For example
If we have 10 points then maximum possibilities = 10
and minimum = 3

similarly for 5 points
Max = 5, Min = 3

for 19
max= 19 Min = 3
