- Question is to find the order/rank of 1457236...
thus
1 2 _ _ _ _ _ =5!=120
1 3 _ _ _ _ _ =5!=120
1 4 2 _ _ _ _ =4!= 24
1 4 3 _ _ _ _ =4!= 24
1 4 5 2 _ _ _ =3!= 6
1 4 5 3 _ _ _ =3!= 6
1 4 5 6 _ _ _ =3!= 6
hence next series will be
1 4 5 7 2 3 6
Thus it is 120+120+24+24+6+6+6=306
and hence 1 4 5 7 2 3 6 will be 307th

- since orde is 1234567
now (1234)(567) in this 567 can arrange in 3! way =6 ways.
now (124)(3567) can arrange in 4! way =24 ways.
now (14235)(67) can arrange in 2! way =2 ways.
now (1425)(367) can arrange in 3! way =6 ways.
now (14523)(67) can arrange in 2! way =2 ways.
now (14527)(36) in this 36 can arrange in 2! way =2 ways.
now last is 1457236 can be considered as 1.
so orde is=6+24+2+6+2+2+1=41. - 11 years agoHelpfull: Yes(3) No(11)
