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

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
