Plz sir solve this expression 4/5(4/5(4/5(4/5(4/5x-1"bar"-1)-1)-1)=5k k= no of item we get x = 3121 Add whatever you love to the Yahoo! India homepage....
The answer is 22 Â xy * ab = pqr p=2r and p=2x so r=x Also r=2y so... x=2y... Now q=2(x+y)...Q is a single digit no. piu x=2y ..we get q=6y..q being single...
Well friend i got some other answer XY * AB = PQR is the given expression. We shall start working from the values for which we know or additional info given in...
As per ques.... xy * ab = pqr  pqr = 100p+10q+r       = 200r+20(x+y)+2y       = 200x+20(x+y)+2y       = 220x+22y       = 22(10x+y) ...

1. Let the total distance be x km. x-(21x/50 + 4x/50)=2 x/2 = 2 x=4 km. 2. speed = distance/time s=420/t s+10 = 420/(t-1) substituting value of s in 2nd...
 I think the answer to this question is 4.the last digit appears to be 0.it is div by 2,10,5.but it cannot be said that it wud certainly divide by 4. From:...
Hai arun, I got a different answer.. Let us first see the little ferret theorem it says when ever a number say xyz^xyz to be divided by a number 'N' (only for...
as problem is            XY*AB=PQR.  and R=2Y,        P=2R=4Y.        Q=2X+2Y,       2X=P so Q=6Y.  as it is also given...
2^256 = (2^4)^64=(17-1)^64 all the terms are divisible by 17 except (-1)64. Hence the remainder is 1. Rahil Sahu Naval Architect VEDAM Design & Techinal...
Hi Question is not very clear...Can u please put in a "screen shot" manner..Just take a screen shot of the question and paste it in the mail... ... From:...
X, Y, a, b, p q, r  are single digit numbers. P = 2r, r = 2y, implies P = 4y  P = 2x, P = 4y imples x = 2y  q = 2(x+y) implies q = 6y  As x,y & q are...
since pqr is "2x 2x+2y 2y" p and r are even and q is addition of these  numbers . and 2x,2y and 2x+2y must be a single digit . so totally there are 2,4,6,8....
A five digit number is taken .Sum of first four (excluding the number at the unit digit ) ewuals sum of all the five digits .which of the folliwing will not...
Hey by Euilers theorem L(16) = 2^4( 1-1/2)= 2^3 = 8 it states that N ^ L(16) divided by 16 leaves a remainder of 1 and since 256 is a factor of 8 (8*32=256) ...
OOOps sorry for the typographidal error By euiler theroem L((17)= 16. 16 is a factor of 256 hence 2^256 when divide bye 17 leaves a remainder of 1 Kindly...
Hi, Interesting way to solve the question but you made a calculation error in this step: ((5^9)^56)/11 -> (5*(*3^4*)^56)/11 It should have been: ((5^9)^56)/11...
