Let the average attendance for the 5 days be 2x. Thus, the total attendance over the weekend was x. The total attendance over the 7 days is : 5*2x+x = 11x.

Thus required percentage :\frac{x}{11x}*100 = 9% approx.

Let no. of attendees during weekdays = 50 (Average of 10 per day)

No. of attendees during weekend = 5

So required ratio = \frac{5}{55}*100 \approx 9%

Answer is A

Since it's a percentage problem, we can assign nos as per our convenience
Let's assume attendance for Saturday and Sunday combined = 100

"Attendance at a library for Saturday and Sunday combined was 50% of the average attendance for the preceding 5 days"

As per above statement, attendance on Saturday and Sunday combined was 100, then attendance on each weekday - 200

The question asks for percentage of weekend attendance over that of entire week (Attendance of sat and sun/attendance of entire week)*100
Hence, for five days of the week (Mon-Fri) - 200*5 = 1000
Attendance for Sat and Sun = 100
Attendance of entire week = 1000+100 - 1100
Therefore percentage of .... = (100/1100)*100 = 9 (approx)

Let the 5 days attendance = w

Average = \frac{w}{5}

Weekend attendance = 50% of average

= \frac{50}{100} * \frac{w}{5}

= \frac{w}{10}

Total attendance = w + \frac{w}{10} = \frac{11w}{10}

Weekend attendance percentage

= \frac{\frac{w}{10}}{\frac{11w}{10}} * 100

= 100/11 = 9

Answer =A
