Answer 1

Answer:

Hlo mate**!!!! here is ur ans....

Step-by-step explanation:

4 examiner working for 8 days(5 hours a day)

thus,

1 examiner=8*5=40 hrs/person

Now,

2 examiner working for 20 days(x hrs a day) to have twice the work.

thus,2*x hrs spent each day

We need 160 hrs.Working 2 hrs the duration will be:

160/2*x=20

=>x=4 hrs

Twice work is done,thus,time=4*2=8 hrs.
