in an office one day 10% of the staff members were on leave in the morning session .the same day 20% of the staff who were on leave came for the afternoon session.if the total strenght of office is 33 then how many were present in the evening session?(the persons who were present in the morning session also present it the afternoon) -

please can you anwer this fast i have exam tom.please

Total number of members = 300
Members who are absent in the morning = 10% of 300 = 300* 10/100=30
Number of members who are present in the morning = 300-30=270

Given 20% of 30 members are present in the afternoon.
So number of members present in the afternoon = 20% of 30 = 30* 20/100=6

So total  number of members present for evening =
=Number of members who are present in the morning+number of members present in the afternoon
=270+6
276

Is the total strength of the office 300???pls check if yes, then the answer is:

Percentge of staff absent in the morning session = 10%

Strength of the office = 300

Therefore, no: of staff members present in the morning session = 30/ 100 of 300 = 30/100 x 300

= 30

Percentge of staff members present in the afteroon session, who were present in the morning session= 20%

No: of staff members present in the afteroon session, who were present in the morning session= 20/100 of 30

= 20/100 x 30 = 6

No: of staff members present in the evening session, who came in the morning session = 300 - 30 = 270

No of staff members present in evening session= 270 +6

= 276
