- ans 280sec
to make 141 pieces , he has to cut 140 times
so 140*2=280 - 9 years agoHelpfull: Yes(18) No(0)
- ans will be 280 sec
as o of cut = no of peices -1
so 140
now time taken fot each bar to cut= 2sec
so total time in sec= 2 * 140= 280 - 9 years agoHelpfull: Yes(3) No(0)
- he takes 2 sec to cut a piece, means 2 pieces are cut in 1 sec, similarly 3 pieces are cut in 2 secs, so to cut 141 pieces he would require 141-1=140 sec=2min 20 secs.

- 9 years agoHelpfull: Yes(0) No(1)
- 280 . 140 cuts make 141 cut
- 8 years agoHelpfull: Yes(0) No(0)
