Goh Pei Ming's son finishes PSLE, but has to solve 'final Math question' to unlock laptop
It was inspired by one of the questions on this year’s PSLE Maths examination.
Goh Pei Ming's son recently completed the Primary School Leaving Examination (PSLE) and is now getting his laptop back. Goh, a Member of Parliament (MP) and Senior Minister of State, expressed his pride in his son's accomplishment on Instagram. However, he left one last task for his son before granting laptop access again. Goh, who was away on a business trip, left a note on his son's laptop containing a challenging mathematics question.
The note praised his son's effort, discipline, and perseverance during the PSLE preparation period. It detailed how the son devoted 4 hours daily to revision, occasionally giving in to temptation and only studying for 3 hours. Goh then posed a problem: to determine the minimum number of days (N) his son must have resisted using his laptop to achieve more than 90 hours of total revision time.
The password for the laptop would be N multiplied by 9999. The netizens congratulated Goh and his son on the milestone, while some found the question rather perplexing. The solution to the problem is N = 16.
