Brain Teaser
You have 5 jars of pills. Each pill weighs 10 grams, except for contaminated pills contained in one jar, where each pill weighs 9 grams. Given a scale, how could you tell which jar had the contaminated pills in just one measurement?
(Ed note: I failed at this one).

Director’s Roundup
- President Carmel:
- Remember to visit Worklocker to try on the new shirt for size. The shirt brand is Patterson, but the Worklocker staff should know if you say they are for Rotary. A pocket will cost $15 to be paid to the Treasurer. Notify Brian about the size, your preferred name and if you want a pocket. Please do this soon so we can make the order.
- Treasurer Len:
- Books have been given to the auditor.
- George
- RYPEN applications close on 11 October. We have 2 applicants at the moment.

Sergeants Session – Andrew Raadgever
Andrew was unusually ruthless, fining most for their foibles. This included a Riley owner and a green ute owner with 410km on the clock. He noted the number of dead roos between Tocumwal and Narrandera (26 but only Andrew would count them). We got a bit sidetracked with the pronunciation of some town names. The cross-fine session highlighted the driving skills of some members who have passed license re-tests.

Member Update – Greg Brown
Greg noted that he has been a member since 1984 but that his association with Rotary commenced with an application to be a member of a GSE team which saw him go to Sweden in 1979. He was Club President in 1979. In 2010 he nominated for District Governor and so began a 4-year training that culminated in him being District Governor of District 9700 in 2012/13. This included attendance at the World Convention in San Diego, where he met with other District Governors and the World President.
Greg has enjoyed his time and the fellowship in Rotary.
A recent highlight was when he was asked to be a member of the Roxy Re-Development Committee. He is convinced that the New (Old) Roxy will be a great centre-piece for the town.
His philosophy: Do not dwell on the past. Look to the future. No regrets.

A Gift to a Mother
Three sons left home, went out on their own and prospered. Getting back together, they discussed the gifts they were able to give their elderly mother.
The first said, “I built a big house for our mother.”
The second said,” I sent her a Mercedes with a driver.”
The third smiled and said, “I’ve got you both beat. You know how Mom enjoys the Bible, and you know she can’t see very well. I sent her a brown parrot that can recite the entire Bible. It took 12 years to teach him. I had to spend $100,000 a year for 10 years, but it was worth it. Mom just has to name the chapter and verse, and the parrot will recite it.”
Soon thereafter, Mom sent out her letters of thanks:
“Milton,” she wrote, my first son, “The house you built is so huge. I live in only one room, but I have to clean the whole house.”
“Marvin,” she wrote to another, “I am too old to travel. I stay home all the time, so I never use the Mercedes. And the driver is so boring!”
“Dearest Melvin,” she wrote to her third son, “You were the only son to have the good sense to know what your mother likes. That chicken was delicious.”

Solution: To find the contaminated Jar, follow this step-wise approach.
- Step 1: Take out 1 pill from jar 1, 2 pills from jar 2, 3 pills from jar 3, 4 pills from jar 4 and 5 pills from jar 5.
- Step 2: Put all these 15 pills on the scale. The correct weight is 150 (15*10). But one of the jars has contaminated pills. So the weight will definitely be less than 150.
- Step 3: If the weight is 149 then jar 1 has contaminated pills because there is only one contaminated pill. If the weight is 148 then jar 2, if the weight is 147 then jar 3, if 146 then jar 4, if 145 then jar 5.
