• 65)(9,3,6),(21,9,12),(33,15,18),(45,21,24)(z,y,x),...?
  we have to find z y x.
  Z must be greater than x and y
  x must be greater than y
  dont be confuse k..... last two digits must be big n middle one small
  6+3=9
  12+9=21
  18+15=33
  24+21=45
  
  finding x -series (6,12,18,24) adding +6 to each number =6+6=12, 12+6=18 18+6=24 24+6 =30=x
  finding y -series (3,9,15,21) adding +6 to each number =3+6=9 .....so on....21+6 =27=y
  finding z series 30+27=57
  
  as i told u ppl. middle must be small and first one is big number so series is (57,27,30) ANS
  
  do it on paper u will wont confuse.
