here first 2 hours to prepare a technical document and half-an-hour to screen it ..so total 2 1/2 hour work is need to 1/2 hour presentation....
For 7 1/2 hours presentation...
1/2 hour presentation-------------->>2 1/2 hour work done
7 1/2 hr presentation --------------> x hours work done
just do cross multiplication u will get x value i.e. required amount of time
since 7 1/2 hours contains 15 half-an-hours ...15* 2 1/2===== 30+7.5===total 37 1/2 hours

for 1/2 hour technical we need =2 1/2 hours then 1 hour technical we need exactly 5hours.

then
7.5 presentation 7 .5*5=37.5 hours

For 1/2 hr presentation it takes 2 1/2 hr + 1/2 hr=3hr.
so for 1 hr presentation it takes 6 hr
So for 7 1/2 hr presentation it will take 15*3=45 hr

taking technical document 2 hr = 1/2 hr presentation and technical preparation; .......(i)
and also screening take 1/2 hr for same presentation;

means average 2 1/2 hr = 1/2 hr presentation....(ii)

since he take 5 hr = 1 hr presentation
since 35 hr = 7 hr presentation.

from eq ( ii )
for 7 1/2 presentation = 35+2 1/2 hr = 37 1/2 hr or 37.5 hr
