Out of         100 minutes they study books for      78            minutes

 

out of             1  minutes they study books for   78/100        minutes

 

out of           50 minutes they study books for  (78*50)/100   minutes

 

                                                                      =39             minutes

Answer 3

     If 50 min are 100%

Then x   min are 78%

So we have a proportion: 50/x=100/78

Solve for x

x=78*50/100=3900/100=39 min
