how can I get the same list but ignoring the sublists based on the second value. For example, how can I get the same list avoiding numbers lower than 75 based on the second value (e.g.{firt value,second value,third value},{firt value,second value,third value}.....)as to get:

In the same way how can I get the same list based on the second when the second value is between 75 and 55.

Thank you in advanced
