4 :: Cube has colors blue, red ,yellow each on two opposite sides. cube is divided into "32 small cubes and 4 large cubes". question: how many cubes (on 36 cubes) have blue at least one side. how many cubes have colors on two sides?
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.
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.
5 :: A, B, C, D went to a hotel and planned to share the bill equally. But afterwards they changed their plan and to pay proportional to consumption A paid 240, B & C paid equally, D paid only half the amount that he should have paid based on the first plan. What is the amount paid by B?
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

Ans: 440s
Let velocity of A,B and C be a,b,c resp.
2(pi)r/88 = a+c
2(pi)r/110 = b+c
we have to find 2(pi)r/a-b

12 :: Each of the followed paired numbers have a relationship thats the same for all of the paired numbers. What is the missing number?
{4, 100} {7, 111} {8, 1000} {1, 1} {12, 1100} {2, ?}
(8, 1000) (2^3, 10^3)
(4, 100) (2^ 2, 10^2)
(1,1)( 2^0, 10^0)
(2,?)( 2^1, 10^1)
(4, 100) (2^ 2, 10^2)
(1,1)( 2^0, 10^0)
(2,?)( 2^1, 10^1)
14 :: If there are 2 wheelers and 4 wheelers parked in a school located at the heart of the city, find the number of 4 wheelers parked there if there were 58 wheels are parked there?
we check according to the answers for eg. 14x4=56 and 1x2=2 then also total 58 wheel
thus 14 is the max no of 4 wheelers.
But less than 14 also possible so goes through the option.
thus 14 is the max no of 4 wheelers.
But less than 14 also possible so goes through the option.
15 :: 10 Men Can Complete A Piece Of Work In 15 Days And 15 Women Can Complete The Same Work In 12 Days. If All The 10 Men And 15 Women Work Together , In How Many Days Will The Work Get Completed?
1 women=1/15
1 men = 110
if both men and women works together they will complete the work by 6 days
=(1/10)+(1/15)
=(15+10)/150
=25/150
=1/6 (i.e)
6 days
1 men = 110
if both men and women works together they will complete the work by 6 days
=(1/10)+(1/15)
=(15+10)/150
=25/150
=1/6 (i.e)
6 days
16 :: The IT giant Tirnop has recently crossed a head count of 150000 and earnings of $7 billion. As one of the forerunners in the technology
front, Tirnop continues to lead the way in products and services in India. At Tirnop, all programmers are equal in every respect. They
receive identical salaries ans also write code at the same rate.Suppose 12 such programmers take 12 minutes to write 12 lines of code in
total. How long will it take 72 programmers to write 72 lines of code in total?
The formula for this question is M1*D1*W2=M2*D2*W1
So putting all these values we get the answer to be 12 minutes
So putting all these values we get the answer to be 12 minutes
17 :: in pure milk if 20% replaced by water and in this again 20% is replaced by water and again 20% is replaced by water then what is the proportion of milk in that mixture?
100-20%=80% ; 80-20%=64 ; 64-20%= 51.2%
18 :: In a right-angled triangle, the square of the hypotenuse is twice the product of the other two sides. Then one of the acute angles of the triangle is…
A. 450
B. 300
C. 600
D. 150
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;
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;
19 :: There are 76 persons. 53 can read Hindu,46 can read times,39 can read Deccan and 15 can read all.if 22 can read Hindu and Deccan and 23 can read Deccan and times then what is the number of persons who read only times and Hindu?
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...
Since H+D=22
T+D=23
ALL=15
then 76=22+23+15+(H+T)
H+T=76-60=16...
20 :: Three numbers are selected at random without replacement from n number,what is the probability that the first number drawn will be the smallest and the second is the largest?

23 :: One man or two women or three boys can do a work in 44 days then one man, one women and one boy together can finish the same work in ---- days?
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
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

ii) and sum of the first two digits is less than or equal to the last digit
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)
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)
25 :: A cube has a side of 4cm.b The cube is painted red on all six side. This cube is then cut into 125 smaller cubes. How many of these smaller cubes will have only one side of their sides painted?
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, thus:
- 27 smaller cubes have no red paint on them
- 98 smaller cubes have some red paint on them
How many of these smaller cubes will have only one side of their sides painted?
- 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
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, thus:
- 27 smaller cubes have no red paint on them
- 98 smaller cubes have some red paint on them
How many of these smaller cubes will have only one side of their sides painted?
- 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
