Answer :
If you paint the cube such that:
- Blue and Blue are on opposite sides
- Red and Red are on opposite side
- Yellow and Yellow are on opposite side
- And, since the question didnt state where the 32 smaller could be, Im placing the 32 smaller cubes on the sides with Blue paint.
- Thus: 32 cubes have Blue on at least one side.
- 20 cubes have have colors on two sides.

Answer :
No it must be 16
Since H+D=22
T+D=23
ALL=15
then 76=22+23+15+(H+T)
H+T=76-60=16. Reasoning Interview Questions -
Answer :
3 sides are p,q, sqrt(2pq).
now if it is sright-angle then 2pq=p^2+q^2;
cos(angle)=sqrt(p/2q);
sin(angle)=sqrt(q/2p);
So sin(2*angle)=2*sin(angle)*cos(angle);
sin(2*angle)=1;
So angle=45;

Answer :
ans -160
jus suppose 1st plan all paid x rs means individually x/4
2nd plan
x eqals= 240+x/4+x/4+x/8
solving x equals 640
so
paid by B is x/4

Answer :
Train crossed the car with less speed in less time and the car with high speed in more time.i.e train and two cars going in the same direction.
hence 1st car
L/((S-45)*5/18)=36 i.e L=10S-450
similarly for 2nd car
L=15S-750
BY solving these two equations we get length of the train L=150mtrs

Mathematics Interview Questions -
Answer :
Exactly 24 days...
1 man do 1/44 job per day.
2 woman do 1/44 job per day.
3 children do 1/44 job per day.
so
1man , 1 woman , 1 child.
1/44+1/88+1/132 job per day
so 11/264 = 1/t where t is the time taken.
now 264/11 = 24 = t
Reasoning Interview Questions -
Answer :
our number is xy9
now if x is 0 then y has 10 options
now if x is 1 then y has 9 options (except 9)
now if x is 2 then y has 8 options (except 9 and 8)
.
.
.now if x is 9 then y has 1 option (that is 0)

Answer :
The 4cm cube is divide into 125 smaller cubes:
that means that the 4cm cube = 5 smaller cubes in height, width, and depth
Also, given that the 4cm is painted red on all six side:
- only those smaller cubes that touch no outer surface will be free of red paint,
- 27 smaller cubes have no red paint on them.
- 98 smaller cubes have some red paint on them.

Question 21. How Many Of These Smaller Cubes Will Have Only One Side Of Their Sides Painted?
Answer :
only those smaller cubes that do not touch the edges of the 4cm cube will have only one side painted, thus:
- 54 smaller cubes have only one side painted
- 36 smaller cubes have two sides painted
- 8 smaller cubes have three sides painted

Answer :
4.5 kms
54 kilometers per hours = 54000 meters per hour
54000 meters / 60 minutes = 900 meters per minute
900 meters * 5 minutes of traveling time = 4500 meters travel
4500 meters = 4.5 kilometers traveled in 5 minutes -
Answer :
3
Divide the 7p into 1p, 2p, and 4p.
1p = 1p
2p = 2p
3p = 1p + 2p
4p = 4p
5p = 4p + 1p
6p = 4p + 2p
7p = 4p + 2p + 1p

Question 29. How Can A Cake(circular) Be Cut Into 8 Pieces By Making Just 3 Cuts?
Answer :
Make two cuts to divide the cake into 4 (cutting on the diameter of a circular cake, the cuts perpendicular to each other). Now, place the 4 sectors of the cake one over the other. Make a cut such that the cut goes throw the centre cutting each of the cake sectors into half. So now we have done 3 cuts. Each sector is cut into two so 4*2=8.

Question 36. 9,18,21,25,20, What Is The Next Number In The Above Sequence?
Answer :
ans= 25
bcoz, 3*3=9
3*6=18
3*7=21
5*5=25
5*4=20
so like(3*6 and 3*7 it will be 5*4 and 5*5 mens increment by 1)
Teacher Interview Questions -
Answer :
Ans: 3
When the number is divided by 3D we got 21. Means the number itself is 21 and 3D >21.
when 21/D, remainder is 8.
So D = 21-8 =13.
now (21*2)/(13*3), Remainder is 3.
