Number System - Questions & Discussions

Try these-----
(1) For how many values of a natural number 'n', the LCM of 6^6, 8^8 and 'n' is 12^12?
(a)1
(b)6
(c)24
(d)25
(e)36
(2) Suppose a function f(x) is defined over the set of natural numbers...
as follows....
f(1)=1
f(2)=1
f(3)=-1
and f(n)= f(n-1)f(n-3); for n>3.
find f(694) + f(695).
(a)-2
(b)-1
(c)1
(d)2
(e)3


And puys full explanation please........
:
IT IS BETTER TO FAIL IN DOING SOMETHING THAN TO EXCEL IN DOING NOTHING.


for
Q1 .. 25 VALUES
Q2 .. 2..
if correct will post the approach..

(a)1
(b)6
(c)24
(d)25
(e)36

for
Q1 .. 24 VALUES



i think this should be 25..

approach : 2^ (0-24) .. so 25 values

(2) Suppose a function f(x) is defined over the set of natural numbers...
as follows....
f(1)=1
f(2)=1
f(3)=-1
and f(n)= f(n-1)f(n-3); for n>3.
find f(694) + f(695).
(a)-2
(b)-1
(c)1
(d)2
(e)3



cyclicity of 7 ...

f(694) + f(695) = f(1) + f(2) = 1 + 1 = 2

Answer = 25 {n = 2^k * 3^12 } where k = 0,1,2,3,4,....,24

The remainder will be 7

Please post the approach too. I did using very long method, to find the cyclicity of 18.
Calculate the remainder when 7777777......(37 times) is divided by 19?

PS: I dont know whether it has been posted earlier.

why not 10?? pls xplain

64,65,66,67,68,69,70,71,72,73
63,64,65,66,67,68,69,70,71,72
62,63,64,65,66,67,68,69,70,71
61,62,63,64,65,66,67,68,69,70
60,61,62,63,64,65,66,67,68,69
59,60,61,62,63,64,65,66,67,68
58,59,60,61,62,63,64,65,66,67
57,58,59,60,61,62,63,64,65,66
56,57,58,59,60,61,62,63,64,65
55,56,57,58,59,60,61,62,63,64


The highest power of 2 goes to be 13, which could be seen only in 4 sets and not 10.

Hello Puy's Help me out in this question ???

1 : A is going to pay 836 to B after 9 months at a rate of 6% annual SI. B is going to pay 783 to A after 15 months at a rate of 7% annual SI. If they both decide to settle the amount right now,who will pay what amount to whom????

2 :Jubin buys a car for Rs 400000. What is the approximate yearly installment amount to be paid by him, if at 12% p.a. compounded annually, he repays the remaining amount in 3 more years ?

guys give the explaination also along with ur ans..

7*8*8*8=3584

A is a 4 digit +ve interger and B is a 4 digit +ve integer formed by reversing the digits. A-B is divisible by 45. Find the no.of possible values??

could u help me with this guys...
