13. A permutation is often represented by the cycles it has. For example, if we permute the
numbers in the natural order to 2 3 1 5 4, this is represented as (1 3 2) (5 4). In this the (132)
says that the first number has gone to the position 3, the third number has gone to the
position 2, and the second number has gone to position 1, and (5 4) means that the fifth
number has gone to position 4 and the fourth number has gone to position 5. The numbers
with brackets are to be read cyclically.
If a number has not changed position, it is kept as a single cycle. Thus 5 2 1 3 4 is represented
as (1345)(2).
We may apply permutations on itself If we apply the permutation (132)(54) once, we get 2 3 1
5 4. If we apply it again, we get 3 1 2 4 5 , or (1 2 3)(4) (5)
If we consider the permutation of 7 numbers (1457)(263), what is its order (how many times
must it be applied before the numbers appear in their original order)?

1.Write the prime factorization.

600 = (2^3)(3^1)(5^2)

The number of divisors (including 1 and the number itself) is the product of one plus the exponents.

(3+1)(1+1)(2+1) = 24
-------------
2.The sum of the first N square numbers is:
N*(N+1)*(2N+1)/6
So putting N = 20 gives 2870.
----------
3..Consider (1+x)n=C0+C1x+C2x2+…..+Cnxn …….(1)

Differentiating w.r.t x we get

n(1+x)n−1=C1+2C2x+3C3x2+…..+nCnxn−1

Multiplying by x on both sides,

x.n(1+x)n−1=x.C1+2C2x2+3C3x3+…..

Now again differentiating w.r.t to x

n(1+x)n−1+n(n−1)x(1+x)n−2=C0+22C1x+32C2x2+42C3x3…..

Putting x = 1, we get

n(n+1)2n−2=C1+22C2+32C3+42C4

Now substituting n = 28

28(28+1)228−2 = 812.226 = 406.227

13. A permutation is often represented by the cycles it has. For example, if we permute the
numbers in the natural order to 2 3 1 5 4, this is represented as (1 3 2) (5 4). In this the (132)
says that the first number has gone to the position 3, the third number has gone to the
position 2, and the second number has gone to position 1, and (5 4) means that the fifth
number has gone to position 4 and the fourth number has gone to position 5. The numbers
with brackets are to be read cyclically.
If a number has not changed position, it is kept as a single cycle. Thus 5 2 1 3 4 is represented
as (1345)(2).
We may apply permutations on itself If we apply the permutation (132)(54) once, we get 2 3 1
5 4. If we apply it again, we get 3 1 2 4 5 , or (1 2 3)(4) (5)

13. A permutation is often represented by the cycles it has. For example, if we permute the
numbers in the natural order to 2 3 1 5 4, this is represented as (1 3 2) (5 4). In this the (132)
says that the first number has gone to the position 3, the third number has gone to the
position 2, and the second number has gone to position 1, and (5 4) means that the fifth
number has gone to position 4 and the fourth number has gone to position 5. The numbers
with brackets are to be read cyclically.
If a number has not changed position, it is kept as a single cycle. Thus 5 2 1 3 4 is represented
as (1345)(2).
We may apply permutations on itself If we apply the permutation (132)(54) once, we get 2 3 1
5 4. If we apply it again, we get 3 1 2 4 5 , or (1 2 3)(4) (5)

55th word of SHUVANK in dictionary?? ( 1 Marks )
(1) AHSNKUV
(2) AHNKSVU
(3) AHNKUSV
(4) AHNKUVS
how to find the word
Reply Like? Yes | No   
karthikeyank   11 years ago
Ans is:AHSNKUV
Words starting from A are=A _ _ _ _ _ _ Since we have 6 places empty and 6 characters remaining so these 6 characters can be arranged by 6! ways=720.
But since we have to find the 55th word we'll consider A as first and then proceed!!
Now AH _ _ _ _ _ 5! ways=120 so AH included
Now AHK _ _ _ _ 4! ways=24 (the words starting from AHK are 24)
AHN _ _ _ _ 4! ways=24 (the words starting from AHN are 24)
Till now we covered 48 words but we have to find 55th
Now AHS _ _ _ _ 4! again (not counted)but we have to find just 55th word so we have to select AHS and now proceed with AHS.
AHSK _ _ _ 3!=6 (Till now total words=24+24+6=54)
It means next word is the word we are looking for!!
Next word is AHSNKUV

hi sir tell me the answer for this question & solution also i want.What will be the last two digits of 5306^214
Reply Like? Yes | No   
APOORV   11 years ago
5306^214 means calculating 6^214
from cyclicity method we know that the last digit of the given ques will be 6
we again apply cyclicity for number 6
6^1=6
just see only last 2 digits
6^2=36
6^3=16
6^4=96
6^5=76
6^6=56
now at 6^7 we get again 36 that the cycle repeats at 5 times power solving process completes. so cycle occurs after every 6 itterations
hence 214/6= gives remainder 4... so counting from 6,36,16,96 we get 96 at fourth position.. so 96 will be at last position..
to clarify more u must read about cyclicity problems,,, where ques are about to calculate the unit digit values.
answer is 96

Sqrt(3)/2 * one side of the equilateral triangle = 6+3 = 9[Vide the 2:1 property of equilateral triangle and I am not able to show you the appropriate diagram here]

the center of circle and centroid of triangle are the same point.
centroid divides the median into ratio of 2:1.
radius = 6
(2/3)part of median is radius
2/3 of height = 6
height = 9
√3/2 * side = height=9
side = 6√3 cm

A^2+B^2+C^2=532
putting the values we get
(9/4)* B^2 + B^2 + (2/3)* B^2 = 532
solving this you will get B^2=144
so B=12
put its valus at place of A and C
u will get A=18, B=12 ,C=8... your required answer is 12 :)

Let the no of mangoes he took from tree be equal to x. Thus, the no of mangoes he has after:
1st step=x/2+1
2nd step=(x/2+1)/2+1
3rd step=((x/2+1)/2+1))/2+1 and so on.
The final equation is:
x(1/2^1+1/2^2+1/2^3+.....+1/2^100) + (1/2^1+1/2^2+1/2^3+.....1/2^99) + 100 = 2

Rohit Shaw   11 years ago
say the boy took 'x' number of mangoes.
after step1: he had : - x/2+1= (x+2)/2
after step2: he had : - ((x+2)/2)/2+1= (x+2^1+2^2)/2^2
after step3: he had : - (x+2^1+2^2+2^3)/2^3
.
.
.
.
after step n : he had : - (x+2^1+2^2+2^3+........+2^n)/2^n
=( x + 2 ( 2^n - 1 )/(2-1) ) / 2^n
=( x + 2^(n+1) - 2) / 2^n

given : ( x + 2^(n+1) - 2) / 2^n = 2

=> x + 2^(n+1) - 2 = 2^(n+1)

Mr. Beans visited a magic shop and bought some magical marbles of different colours along with other magical items. While returning home whenever he saw a coloured light, he took out marbles of similar colours and counted them. So he counted the pink coloured marbles and found that he has bought 25 of them. Then he counted 14 green marbles and then 21 yellow marbles. He later counted 30 purple coloured marbles with him. But when he reached a crossing, he looked at a red light and started counting red marbles and found that he had bought 23 Red marbles. As soon as he finished counting, it started raining heavily and by the time he reached home he was drenched. After reaching home he found that the red, green and yellow marbles had magically changed colours and became white, while other marbles were unchanged. It will take 1 day to regain its colours, but he needs to give atleast one pair of marbles to his wife now. So how many white marbles must be choose and give to his wife so as to ensure that there is atleast one pair of red, yellow and green marbles ?

let p be the amt..
(p*5*4)/100=1020-p =>p=850/

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

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

Niveditha Ravichandran   11 years ago
volume of cuboid= 5*6*7 = 210
volume of hollow part = (5-2)*(6-2)*(7-2)=3*4*5 = 60

so outermost layer removing the hollow part = 210-60 = 150 cubic m

small cube volume = 0.03 cubic m
so number of small cubes required = 150 / 0.03 = 15000 / 3 = 5000

ans b) 5000

Devendra Marghade   11 years ago
c) 10560
Curved surface area of cylinder= 2*Pi*r*h
Here r=2.1 ,h=20
So area=2*(22/7)*2.1*20= 264 sq. m.
Cost @40 rs./sq.m.=264*40=10560
