1. A,B and C are 8 bit nos.they are as follows:
A=11000101
B=00110011
C=00111010
find ((A-C)UB)
THE OPTIONS ARE
1)55 2)64 3)32 4)53
ANSWER=55
ANS-- 11
as A is short by 10- he has shot 1
as B is short by 2 - he has shot 9
9+1=10 10<11
this is basically binary operation
n-intersection i.e.LOGICAL AND
U -union i.e. LOGICAL OR
AnB= 01011010
((AnB)uC)=01111111
Answer:b:3 P.M.
Assumptions:
Distance between two points where Bus meets auto=x
Distance between the point where bus meets auto for the second time and Amritsar=y
velocity of bus=Vb
velocity of auto=va
vb=x/2
va=x/4
y=0.5*vb=05*x/2
time taken by auto for covering the distance y=y/va=1 Hour
hence time at which auto reaches Amritsar=2 P.M.+1 hour=3 P.M.
A - C = 10001011
& (A - C) U B =
1 0 0 0 1 0 1 1
0 0 1 1 0 0 1 1
==========
1 0 1 1 1 0 1 1
HENCE,
ANS = 10111011
6. A building with height D ft shadow up to G. A neighbor building with what height shadow C ft is?
G shadow for height D ftC shadow for height = D*C/G
The Answer is 6:40 AM
The destination place is 80 degree west to the starting place. Hence the time difference between these two places is 5 hour 20 min. (=24hr*80/360).
When the flight landed, the time at the starting place is 12 noon (2 AM + 10 hours).
Hence, the time at the destination place is 12 noon - 5:20 hours = 6: 40 AM
9. How many positive integer solutions does the equation 2x+3y = 100 have?
a) 50
b) 33
c) 16
d) 35
Its very simple... See by observing that in 2x+3y=100 2x is always even and 100 is also even so u need to have 3y also positive. so within 100 3 can be multiplied by 100/33 times to get an even number. So (b) 33 is the answer.
X = 4 Hence Y = 36
so option 1,2&3 are correct
no shankar4u ur wrong in ur calculation..... its ((A-c)B)
ie
197-51=146
146+58 = 204
it need to be 11.cos thr s totally 20 such socks,10 in each color so if we take 11 thr shud be atleat 1pair of same color
14. If G(0) = -1 G(1)= 1 and G(N)=G(N-1) - G(N-2) then what is the value of G(6)?
ans: -1
bcoz g(2)=g(1)-g(0)=1+1=2
g(3)=1
g(4)=-1
g(5)=-2
g(6)=-1
Simple Silly question
Go to river catch fish
4*9=36
7*1=7
2*5=10
36+7+10=53...
see it doesn't matter that wat the time is being taken to fill the bucket.after reaching program it waits there for 10ms and back to the programmer in 20 ms.then total time to get the response is 20ms +10 ms=30ms...it's so simple....
AM=Mr. Aye
AF= Mrs. Aye
BM=Mr. Bee
BF=Mrs. Bee
The possible sequence of matches can be :
AM(Win) Vs.AF
AM(win) Vs. BM
AM Vs. BF(win) Hence Mrs. Bee never lose.
in c++ programming language #incude<iostream.h> is must so it give error
First we are taking the l.c.m of 1-10. the result is 2520.
then being the highest prime number 7.
we will divide 2520 by 7. the result will be 360.
which is the least number divisible by all numbers 1-10 other than 7
20. Find the minimum value of 3x+4y if x^2y^3=12?
by substitution , consider x=2/3 & y=3
satisfyng ,x^2y^3=12;(2/3)^2*3^3=12
so 3x+4y=14
There are seven children ( 3 girls and 4 boys )
The other condition 1,2 or 2,3 is not possible

So 10th letter is 'A'
24. If log 0.317=0.3332 and log 0.318=0.3364 then find log 0.319?
log 0.317=0.3332 and log 0.318=0.3364
then
log 0.319=log0.318+(log0.318-log0.317)
0.3396
