Only in Singapore can a math question from a national examination go viral.

The question in the PSLE math paper was so challenging, it left pupils in tears and parents speechless on Oct 1.

Their reactions aren't too surprising given how 12-year-olds here are being put under so much pressure, thinking this one exam can either make or break their future careers.

The difficulty here is getting caught up with trying to frame the question using algebra
If you keep in mind the fact that Ivan has 40 more 20c coins but must have 40 less 50c coins, the problem becomes easier as you can solve for differences instead of absolutes

What stumped the kids? A question involving Helen and Ivan and over a kilogram of coins.

While there's isn't a need for that many coins on hand in our increasingly cashless society, the pair's solid coin game has sent the nation into a frenzy over the weekend, sparking a flurry of memes.

It isn't only netizens who are in on the act, institutions are also jumping on the trend.

Plenty of memes featuring the exam question were also minted, one referencing the life-and-death drama of South Korean TV series Squid Game, now streaming on Netflix.

Singapore is overflowing today with memes and even marketing cashing in on a tough exam question that caused much distress to students.

Ever since complaints about a particularly difficult math question from Friday’s Primary School Leaving Examination surfaced, people have seized on a confusing question about two people carrying a lot of coins to promote everything from borrowing books to philanthropy.

“It doesn’t matter who has more money because borrowing books from the library is free. You can even do it from home on the NLB Mobile app (and it’ll be 0kg). The end,” Singapore’s Public Libraries wrote yesterday, seizing on the public puzzler for a little PSA (Public Service Announcement).


Helen and Ivan had the same number of coins.

The question, meant for 12-year-old students, asked them to determine the weight and value of 50- and 20-cent coins carried by “Helen and Ivan.”

Hospitals and nonprofits also took the chance to urge followers to practice cleanliness or donate the hypothetical money instead of bothering with the problem. Others like banks and food establishments promoted their services and food.

“They both washed their hands thoroughly with soap after they finished counting the coins. Be like Helen and Ivan,” Singapore General Hospital wrote Saturday.

“It didn’t matter to them who had more money and how much their coins weighed. Helen and Ivan had big hearts and donated their money to Singapore Red Cross, to help uplift the vulnerable at home and abroad,” Singapore Red Cross wrote on Saturday.
