5,15,25,35,45,55,65,75,85,95, (11)
105,115,125,135,145,155,165,175,185,195, (11)
205-----(11)
305--------(11)
405--------(11)
505,515,525,535,545,555,565,575,585,595(21)
605----------(11)
705---------(11)
805------------(11)                       

905--------------(11)

so the ans is 9*11 + 21 = 120

 

i think thats correct
