351^n = (350 + 1) ^n = nc0.(350)^n.(1)^0 + nc1.(350)^(n-1).(1)1...........ncn.(350)^0.(1)^n

All the terms in the expression except for the last are divisible by 7. So irrespective of the number n 351^n gives a remainder of 1.

Similarly

352^n = (350 + 2) ^n = nc0.(350)^n.(2)^0 + nc1.(350)^(n-1).(2)1...........ncn.(350)^0.(2)^n

Here when 352^n is divided by 7 the remainder is 2^n. So when n= 3 the remainder is 8, which when further divided by 7 leaves a remainder of 1.

Therefore the answer is 3 or multiples of 3.

This is about a question listed in the website question bank:

Question
For what value of 'n' will the remainder of 351^n and 352^n be the
same when divided by 7?

(1) 2
(2) 3
(3) 6
(4) 4

Correct Choice is (2) and the Correct Answer is 3

----------------------------------------------------------
----------

Explanatory Answer

When 351 is divided by 7, the remainder is 1.

When 352 is divided by 7, the remainder is 2.

Let us look at answer choice (1), n = 2

When 3512 is divided by 7, the remainder will be 12 = 1.

When 3522 is divided by 7, the remainder will be 22 = 4.

So when n = 2, the remainders are different.

When n = 3,

When 3513 is divided by 7, the remainder will be 13 = 1.

When 3523 is divided by 7, the remainder will be 23 = 8.

As 8 is greater than 7, divide 8 again by 7, the new remainder is 1.

So when n = 3, both 351n and 352n will have the same remainder when
divided by 7.

==========================================================

Alternative approach:

(a � b)� = a� � 2ab + b�

(a � b)� = a� � 3a�b + 3ab� � b�

(a � b)4 = a4 � 4a�b + 6a�b� � 4ab� + b4

so the qsn boils down to "For what value of 'n' will the remainder of
1^n and 2^n be the same when divided by 7?", (since 350 is divisible
by 7). Hence ans is n=3.

i hope this may help u...but 'm not sure whether this is d easiest way out..nyways

when u put x=y=0..this gives eqn whose solution is f(0)= 0 or 2

as its already stated that its not 0..it is 2;

x=y

[ {f(x)}^2-2] =f(2x) ... * (I)

y=1

f(x+1)+f(x-1) =3f(x).... *(II)

f(1) = 3

f(2) = f(1)^2 - 2 =7 ....... by I

f(3) = 3f(2) - f(1) = 18 ....... by II

f(4) = 7^2 - 2= 47 ...... by I

f(6) = 18^2 - 2 = 322 ...... by I

f(8) = 47^2 - 2 = 2207 ....... by I

f(7) = 1/3 * (322 +2207) = 843 ......... by II

Hello All,
           For finding the last two digits(in the multiplication of 2 digit nos) or three digits(in the multiplication of 3 digit nos)...
           Following the method called "Vertically and crosswise".

For example,

multiplying 2 digit nos
56*98

     first multiply 6*8=(4)8.
then multiply the nos cross wise and add them along with carry 6*9 + 5*8 + 4=54+40+4=(9)8 .
then multiply vertically 5*9 =45+9 =54

answer 5488.

In the method mentioned above you carry out multiplication and addition simultaneously.So you can minimise the no of multiplication when you are only bothered with last digits/three digits etc.

now take these nos 34*55*32*43*35*53

34*55 =     70

32*43 =      76

35 *53=      35

76*35 =    60

60*70 =    00

These method applies to all two digits nos.Check it..

Now find last three digits in 543534534*435435345*534534534*345234234.

It is simple and it ll not take more than a minute.

the reason behind the answer D , i presume is not because of the use of the word 'them'.

I think it is because the phrase "they are growing and are seldom in equilibrium" refers to the small businesses , so this pharse should be immediately followed by the small businesses which the phrase rightly qualifies.

If anything wrong, please correct it.

(B) Because they are growing and are seldom in equilibrium, formulas for cash flow and the ratio of debt to equity do not apply to new small businesses in the same way as they do to established big businesses.

(E) New small businesses are not subject to the applicability of formulas for cash flow and the ratio of debt to equity in the same way as established big businesses, because they are growing and are seldom in equilibrium.

D is the right answer, however I don't understand how in D choice "new small businesses" in "Because new small businesses are growing and are seldom in equilibrium" is the object to justify that the usage of pronoun "them"? or how can we justify the use of "them" here?

is the ratio of the radius of the larger circle to that of the smaller circle. if the sum of

the square of hte radii of hte circles is 400 sq. cm...

Let it be r1,r2

so given is 2*pi*(r1+r2) = 176, put pi=22/7, we get r1+r2=28

now, r1^2+r2^2 = 400, so r1=12 and r2=16, which satisfy both the conditions.

So answer is 16/12 i.e. 4/3.

Answer to Rest will follow soon..

My approach is as follows:

F(1,0) è f(1)*f(0) = f(1+0) + f(1-0)

3*f(0) = 2*3 è f(0) = 2

F(1,1) è f(1)*f(1) = f(1+1) + f(1-1)

3*3 = f(2) + 2 è f(2) = 7

F(2,1) è f(2)*f(1) = f(2+1) + f(2-1)

7*3 = f(3) + 3 è f(3) = 18

F(2,2) è f(2) * f(2) = f(2+2) + f(2-2)

7*7 = f(4) + 2 è f(4) = 47

F(4,3) è f(4) * f(3) = f(4+3) + f(4-3)

47*18 = f(7) + 3 è f(7) = 843

This is a derangement problem. If you have read the
derangement principle, the formula is
n!(1-1/1!+1/2!-1/3! ---- + (-1)n )
answer is 9

Hi,

i could ans 2 ques out of ur 6 ques..

pls check whether they r write....

numbers

1.2484 X 36 Y should be divisible by 36...

for this the condition is the no should be divisible by 2,3,8&9..

when X =0 & Y=0, the number is perfectly divisible by all the above.

so the ans is X = Y = 0.

Geometry

1. given the sum of radius sq = 400. let us consider the radius of 1st circl as X and 2nd circle as Y, X as the radius of the larger circle.

so X^2 + Y^2 = 400.

also sum of perimeter of circle is given as 176.

so ( 2 x ( 22 / 7) x X )+ ( 2 x (22/7) x Y ) = 176.

so solving for X & Y, we get X as 16 or 12 & Y as 16 & 12.

since X is larger, take X as 16, so we'l get Y as 12..

ratio becomes 4 : 3

pls reply whether this is right...

use of 'them' in this case is correct. the reason is, the statement discusses about only one thing i.e., established big businesses. it would be incorrect if it discusses about more than 1 thng.

Hi Nanda,

Referring to the solution given by you for the number's prob. I've have certain doubts.

1) Y have you said for the number to be divisible by 36 it has to be divisible by 8 too. It is not necessary (I guess) Or is it??

2) Consider the case where y=8 and x=1 ( since no relation between x and y is given). this pair will also satisfy the conditions.
and in this case value of x-y will be -7. So minimum value will be -7 not 0.

the answer of 32^32^32divided by 9 the remainder ll be 4

soln:::::

the remainder when 32 is divisible by 9 is 5

so remainder is 5^(32*32*32................32 times)

so it is (5^32)^(32*32*32*........31 times)

and remainder of 5^2 is 7

and remainder of 7^2 is 4

and 4^2 is 7

and 7^2 is 4

and 4^2 is 7

so finally 5^32 is 7

and the remainder is (7^32)^(32*32*32*.............30 times)

and now it is (4^32)^(32*32*..........29 times)

so now remainder is (7^32)^(32*32*..........28 times) and so on

so finally we get 4 as remainder that is the answer

Hey Surabhi ..

Kinda can help u from my first hand experience ..

1. Paper will have tough quant section, especially when u have only 2 hours for the paper.

2. Verbal is sought of easy, as cmpared to CAT is a cakewalk, hence the scoring part.

3. DI too forms the easy part....

Conclusions -

Its not possible to do much of maths. So there are precisley two things that can be done - Attempt less of it jst to clear cut offs or the max u can attempt without wasting mch of ur time. And the second some of the very tough questions can be solved by putting answers in the question itself. So i would say ideally , keep 20 min for maths... and keep hopping to search easy questions. that would help u to fetch about 8-10 questions.

For Verbal and DI, i would say last year DI was the easiest, and i attempted in the last... So, have a look at the start. If their a re lots of graphs etal, jump to DI first. But u have to fast with your calculations.

Verbal too was easy, infact these two were scoring.

Rest of the time u can distribute equally in both of these sections.

hope this gives u a strategy to work on.
