# Hong Kong Rid­dles

HK Magazine - - NEWS -

In a re­cent news­pa­per col­umn Legco Pres­i­dent Jasper Tsang set Hongkongers an in­cred­i­bly com­plex math rid­dle (see p.8), ex­plain­ing that if you were able to solve it, you would be able to de­ci­pher the iden­tity of Hong Kong’s next Chief Ex­ec­u­tive. We’ve been in­spired by his ex­am­ple to come up with our very own rid­dles…

1. Hong Kong and main­land author­i­ties have agreed to no­tify each other within 14 days if they de­tain the other’s res­i­dents for crim­i­nal in­ves­ti­ga­tion. If you are ab­ducted at 2am on Wed­nes­day, what is the lat­est that your fam­ily will dis­cover that you have been taken from your home and smug­gled across the bor­der? As­sume nor­mal work­ing hours.

2. It is the July 1 protest march. Or­ga­niz­ers say that 110,000 peo­ple at­tended, while po­lice say that 19,300 protested. On the same day, pro-Bei­jing group the Silent Ma­jor­ity for Hong Kong as­sem­bled over 5,000 peo­ple to take part in an at­tempt to beat the world record for “long­est hu­man chain in the world,” while also singing pa­tri­otic slo­gans. An­swer the fol­low­ing: a) As­sum­ing that both po­lice and or­ga­niz­ers are both in­cor­rect, what is the likely real num­ber?

Given that ev­ery year the po­lice and or­ga­nizer num­bers dif­fer by a large de­gree, what is the state of the arith­metics ed­u­ca­tion sys­tem in Hong Kong?

Why would a lame hu­man chain dis­tract from the

July 1 march? 3. Hong Kong prop­erty sales have fallen 40 per­cent in the past six months com­pared to the same pe­riod last year. If you make \$20,000 per month, cal­cu­late how much il­le­gal ac­tiv­ity you will have to en­gage in if you wish to af­ford a flat worth \$1.5 mil­lion by the time you turn 45. Send a copy of your work­ing to the ICAC. 4. A ticket on the train from Hong Kong to Guangzhou costs \$210 and takes two hours. The new Ex­press Rail Link (XRL) is cost­ing \$84.42 bil­lion to build but will cut the jour­ney to 48 min­utes when it opens in Q3 2018. Cal­cu­late the fol­low­ing: a) What is the ac­tual cost of each minute you save by tak­ing the XRL?

How many reg­u­lar train tick­ets could you buy for the \$84.42 bil­lion bud­get of the XRL?

With the ad­di­tional time saved on the jour­ney, is there ac­tu­ally any­thing worth do­ing in Guangzhou?
