Consider the graph G0 with 3 components which are triangles. G0 has 9 vertices labeled
A to I and 9 edges (A, B), (B, C) … as shown below.
If each vertex of G0 is assigned a red or a green color, then we say that an edge is
colored if its ends have different colors.
Ajai and Rekha color the vertices of G0 in the following manner. Ajai proposes a color
(red or green) and Rekha chooses the vertex to apply this color. After 9 turns, all the
vertices of G0 are colored and the number of colored edges is counted.
Suppose Ajai would like to maximize the number of colored edges while Rekha would
like to minimize the number of colored edges. Assuming optimal play from both players,
how many edges will be colored? Explain ur reasoning.

Here x is missing.
But if we consider p to be x
then option C is correct as its value can be calculated by using statement 1 alone(p=0, p=-2).
and using statement 2 alone(p=0, p=-1) but p have three values so final answer is p= 0, -1, -2.

Arun starts from cochin to trichy @ 11am.He travelled @60 kmph & covered 1/2 the dist in 2 hours.@ what uniform speed should he travel to reach trichy by 4pm? a)60 b)55 C)40 d)45

neha gupta 9 years ago

As Arun has covered half distance in 2 hours by travelling at 60 km/hr
thus total distance = (2*60*2) = 240
now distance to be covered = 120 km
time left = 3 hrs(2 hrs to 11 AM is 1 PM so time left = 4 PM - 1PM = 3 hrs)
speed required = 120/3 = 40 km/hr
so answer is C.

time taken by a = 60min

b is doing work for x min and a and b together doing it for x min
i.e.

neha gupta 9 years ago

Let the distance travelled by thief before being caught be x km
speed of theif = y km/hr
time = x/y ...............(i)
then distance of police = (x + 0.2) km
speed of police = (y + 2) km/hr
time = (x + 0.2)/(y + 2) ..................(ii)
putting (i) and (ii) equal, we get
x/y = (x + 0.2)/(y + 2)
x/y = 0.1 hr = 0.1 * 60 = 6 minutes.

A boat sails downstream from point A to B, which is 10 km away from A, and then returns to A. If the actual speed of the boat(in still water) is 3 km/h, the trip from A to B takes 8 hours less than that from B to A. What must be the actual speed of the boat for the trip from A to B to take exactly 100 minutes ?

Reply Like? Yes (1) | No

Mallikarjuna Reddy 9 years ago

distance is 10 km
boat speed b=3km/h
let stream speed be v
trip from A to B takes 8 hrs less than from B to A i.e.,
time taken for upstream-time taken for downstream=8
t(up)-t(down)=8
=>(10/(3-v))-(10/(3+v))=8
if we solve above eq we will get v as 2
so stream speed=2km/h
from A to B 100 min i.e., 5/3hr
for to reach in 5/3hr let boat speed be u
(10/u-2)=5/3
=>30=5u-10
u=8
so, boat speed should be 8km/h to reach in 100 min

of 21 . What is the remainder left, when twice the number is divided by 3D?

Reply Like? Yes (1) | No

premlata 9 years ago

Let the no. is a
a = Dx +8 (x is the quotient )
a = 3Dy + 21 (y is the quotient )
So from above equations we get
D(x-3y) = 13
becoz 13 is prime, so x-3y has to be 1
let x = 4 and y = 1
We get a = 60 and D=13
2a = 120
So 120 when divided by 3D = 39 (when twice of number is divided by 3D)
we get remainder as 3 (120/39)
So answer is 3

Reply Like? Yes | No

premlata 9 years ago

Distribute 1 chocolate among all four then left chocolates are 11.
case 1 when sana get 3 chocolates: ( 8+4-1)C(4-1) = 11C3 = 165
case 2 when sana get 4 chocolates 10C3 = 120
case 3 sana get 5 chocolates 9C3 = 84
case 4 sana get 6 chocolates 8C3 = 56
so, total ways are 165 + 120+ 84+56 = 425

OR (other approach)

Distribute 1 chocolate to all children and sana get 3 chocolates initially remaining is 8 chocolate.
so, way to distribute is (8+5-1)c(5-1)=495

now subtract upper limit (at most 6 chocolates) from 495 which is (4+5-1)c(4)= 70,

so ans is 425
