Question

please kindly give me answer

Answer 1

Given : The Total Strength of the Office = 400

Given : 20% of the Staff Members are on leave in the Morning Session.

⇒ 20% of Total Staff Members :  $\frac{20}{100}\times 400 = 80$

⇒ 80 Staff Members are absent in the Morning Session

⇒ The Staff Members who are Present in the Morning Session are : (400 - 80) = 320

Given : 10% of the staff, who are on leave came for the Afternoon Session

We found that 80 Staff Members are on leave during the Morning Session

⇒ 10% of Staff Members who are on leave during the Morning Session are :

⇒ $\frac{10}{100}\times80 = 8$

⇒ 8 Staff Members who are on leave during the Morning Session are present in the Afternoon Session.

The Staff Members present in the Evening Session = The Staff Members present in Morning Session + The Staff Members who are on leave during the Morning Session and present in the Afternoon Session

The Staff Members Present in the Evening Session = (320 + 8) = 328
