Today Puzzle #606

Puzzle No. 606 – Thursday 7 November

Happy 150th birthday to Nature magazine, the world's leading multidisciplinary scientific journal that was first published this week in 1869. For the print edition, the global circulation of 52,000 weekly copies is split into three geographic regions: 1. The Americas, 2. UK/Europe and 3. Asia/Rest of the World. The Americas is 51%. With UK/Europe being 27% more than Asia/Rest of the World, how many print copies are in UK/Europe?

Today’s #PuzzleForToday has been set by Bobby Seagull, a school Maths teacher and Cambridge University Doctorate student.

19,760 copies in UK/Europe

UK/Europe and Asia/Rest of the World must be the remaining 49%.

UK/Europe = X and Asia/Rest of the World = Y

X + Y = 49%. X = Y + 27%. (Y + 27%) + Y = 49%

2Y + 27% = 49%. 2Y = 22%. Y = 11%. So X = 38%

38% of 52,000 = 19,760
