In a office work is distribute between p persons. If 1/8 members are absent then work increased for each person
Read Solution (Total 7)
-
- let total % of work is 100%
total person=p
1/8 person are absent of total person . so absent person is 1/8p ie p/8.
left person is, p-p/8=7p/8.
p person do the work 100%
1 person do the work 100*p%
7p/8 person do the work (100*p*8)/7p%=114.28%
work increased for each person is=(114.28-100)%=14.28% (ans) - 10 years agoHelpfull: Yes(33) No(4)
- Total of 8 persons. Persons present = 7.
Work :: 1/persons
Work = 8/7
Excess work 1 - 8/7 = 14.28 or 1/7 - 10 years agoHelpfull: Yes(25) No(2)
- work done by each person=1/p
1/8 mems of total p members are absent.work done by them=1/p*p/8=1/8
work increased for each person=(1/8)/(p-p/8)=1/7p - 10 years agoHelpfull: Yes(7) No(4)
- Let the total work be "w"
then A/c
---------
work load per person = w/p
now when 1/8 of 'p' are absent ,then
new work load per person = (w )/(p-p/8)
i.e. 8w/7
Increased work load= (new work load) - (old work load )
=w/(7p) OR 1/7 of old work load - 10 years agoHelpfull: Yes(5) No(0)
- P PERSON DOES THE TOTAL WORK.
SO 1 '' '' '' 1/P ''
NOW P/8 " " " TOTAL "
SO 1 " " " 8/P "
INCREASE 7/P.. - 10 years agoHelpfull: Yes(1) No(9)
- The answer will be:-
800/(p-8)%
let each person has 100% work.
If 8 person absent then increased work will be 800% and it should be divided in (p-8) person
therefore, increased work per person will be 800/(p-8)% - 10 years agoHelpfull: Yes(0) No(0)
- 1/8 of the absent person has to be done by the remaining seven colleagues, then (1/8) / 7 = 1/56
- 8 years agoHelpfull: Yes(0) No(1)
