Deviation from the mean for the daytime staff = 76 - 65 = 11.
Deviation from the mean for the evening staff = 65 - 60 = 5.
Thus, the ratio of the number of daytime staff members to the number of evening staff members = 5:11.
Answer: C.
Or: (76x + 60y)/(x + y) = 65 --> x/y = 5/11.
Answer: C.

Let "d" is the total no. of day staff
So, total collection in day = 76d .............. (1)
Let "n" is the total no. of night staff
So, total collection in night = 60n ................. (2)
Total Day & Night staff = (d+n) & overall average = 65
So, total collection (Day & Night) = 65(d+n) ........... (3)
(1) + (2) = (3)
76d + 60n = 65d + 65n
11d = 5n
\(\frac{d}{n} = \frac{5}{11}\)
Answer = C
