We can’t subtract the minutes here because


                                              10 minutes < 35 minutes.


              So, we carry 1 hour from 4 hours to minutes side.



              Now, 10 minutes + 60 minutes = 70 minutes


               and   70 minutes – 35 minutes = 35 minutes.






              In the hours we are left with


                                              3hours – 1 hour = 2hours.







                                                     The answer is 2:35.
