In an office, one day, 20% of the staff members were on leave in the morning session. On that same day, 10% of the staff, who were on leave, came for the afternoon session. If total strength of the office is 400, then how many were present for the evening session? (The persons who were present in the morning session were also present in the afternoon session)

Options

A. 360
B. 380
C. 364
D. 328

Answer

D

Explanation

Total strength = 400
20% of 400 = 80
If 80 were absent, then the number people present in morning= 400-80= 320.
In the afternoon, 10% of 80, i.e., 8 turned up.
`therefore ` Number of people present in the evening = 320 + 8 = 328.
Hence, the correct option is (d).
