when m n is divided by 12 remainder 8 when m-n is divided by 12 remainder 6 then mn is

ans is 1.
m+n=20
m-n=18
thus m=19 & n=1
so (m*n)/6=(19*1)/6=1 ans.

m=30
n=2
m+n=32
32/12 remainder 8
m-n=28
28/6 remainder 6
mn=30*2=60
60/6 remainder =0

i got this question in tcs written test.
i took m=31 and n=1
then m+n=32 then 32/12 remainder is 8
and when m-n=30 then 30/12 remainder is 6
so mn=31 then 31/6 remainder is 1
answer:remainder is 1

Answer is 1..
@AMULYA CUTIE : in the question it is given (m-n) divided by 12, not divided by 6. Only the remainder is 6.
therefore (m-n) cannot be 28.

ans:7
i dont know whether i am ryt..
m+n=12x+8,m-n=12y+6
so m=6(x+y)+7,n=6(x-y)+1,
now mn=6(some integer)+7

so the remainder must be 7....correct me if i am wrong

@tejaswini what is the exact ans???
plzzz exaplain method also...
11 years agoHelpfull: Yes(0) No(1)
ans is:0
(M+N)/12=8
(M-N)/12=6
from this we can find M=84 and N=12
(MN)/6=0

when m+n is divided by 12 remainder 8, when m-n is divided by 12 remainder 6,then mn is divided by 6 remainder?
