If m+n is divided by 12 leaves a reminder 8,If m-n is divided by 12 leaves a reminder 6,then If mn is divided by 6 what is the reminder?
Option a)4 b)3 c)2 d)1

• Ans:1
  let m=19 and n=1;
  m+n=20, gives the remainder=8
  m-n=18, remainder=6
  so mn=19*1=19 after division by 6 it wud giv the remainder 1...:)

• m+n = 8 ----1
  m-n= 6 ----2
  using 1 and 2
  
  m=7 and n=1
  m*n =7
  7%6 =1
  ans 1

• if a is quotient then
  m+n=12a+8
  m-n=12a+6
  on solving if a=1
  then m=19 and n=1
  mn=19/6 remainder is 1

• Assume...m=19,n=1 then
  19+1/12=remider is 8 &
  19-1/12=reminder is 6 then
  19*1/6= reminder is 1...
