What are the values of 3 integers a, b and c ? Statement 1: ab=8
statement 2:bc=9

• ab=8
  bc=9
  a=8;b=1;c=9

• If ab=8, possible solutions are (a=1,b=8 ; a=2,b=4 ; a=4,b=2; a=8,b=1)
  bc=9, possible solutions are (b=1,c=9 ; b=3=c ; b=9,c=1)
  
  on;y common solution is a=8,b=1, c=9(Answer)

• 1/ab=8 then b=1/8a-------- eq(1)
  2/bc=9 then b=2/9c--------- eq(2)
  eq(1)= eq(2)
  1/8a=2/9c
  we will get a=9,c=16
  a's value we will put in eq(1)
  now b=1/72

• factors of 8 : 1,2,4,8
  factors of 9 : 1,3,9
  
  common factor is 1 i.e value of b.
  since b=1, then a=8 and c=9.
