SINGAPORE: The man behind the "Cheryl's birthday" viral poser is a mathematics professor from Singapore's National Institute of Education (NIE).

Dr Joseph Yeo Boon Wooi, who is in his 40s, is part of the panel for the Singapore and Asian Schools Math Olympiads (Sasmo), the largest math competition in the country.

He helps set the questions each year for student "mathletes".

 

This year's competition took place on April 8. The puzzle in question was leaked, and subsequently posted on Facebook on April 11 by local TV presenter Kenneth Kong, who initially mistook it for a Primary 5 question.

 

 

Dr Yeo, a recipient of the prestigious Nanyang Excellence in Teaching Award in 2013 and first author of the New Syllabus Mathematics used in secondary schools, said he first chanced upon a Facebook post discussing the birthday logic problem on April 12.

 

But it did not ring a bell until he saw the photo of the question.

It has since been featured on international media such as The New York Times, The Guardian and the BBC, and was a top-trending story on US site Buzzfeed. On April 16, "Cheryl" even got her own cartoon on The New Yorker.

 

The Straits Times caught up with the media-shy math whiz and persuaded him to answer some questions about himself and how he came up with the viral hit that has confounded the world.

 

Dr Yeo's birthday, coincidentally (or not), falls on July 16 – the answer to the puzzle.

My turn to ask question. Can't seem to work it out.

 

Find the missing number

 

Left              Right

8    16          12   34    

9    18            6    ?

 

Find the relationship on the left to apply to the right to get the missing number.

A meteorologist took record of the weather for a number of days. It had been raining 9 times during this period of time, either in the morning or afternoon. There were 11 dry afternoons and 14 dry mornings.

(b) How many days did the meteorologist manage to record?

Need to draw model.

 

D = dry period

R = raining period

 

RRRDDDDDDDDDDDDDD Morning

DDDDDDDDDDDRRRRRR Afternoon.

 

From above, there are 8 dry days, i.e. Morning and afternoon are dry.

End to end, there are 17 days.
