JFYI - If 30.4% of my friends travel by bus, how many friends do I have?

The 'Just For Your Interest' series of posters explores answers to questions I've pondered in my student days and beyond.

Neat question - ratio of bus:others = 30.4:69.6=38:87, therefore total friends 38 + 87 = 125; which checks out: 38/125 x 100 = 30.4%.
