We start by finding out that since there are twice as many oranges as the 5 bananas, this means there are 5*2=<<5*2=10>>10 oranges.
Since there are twice as many apples as the 10 oranges, this means there 10*2=<<10*2=20>>20 apples.
In total, this means there are 20+10+5= <<20+10+5=35>>35 fruits on the display.
