Teacher: Now, understand the problem? Solve this instance: Any Londoner who has taken a trip to almost anywhere else will know just how expensive things are in the city and probably believes that the cost of living seems crippling compared to many other places. But new research shows that the city, which many residents complain is overpriced, is not even in the top 50 most expensive places to live in the world. It shows that goods are cheaper than in New York, Paris, Singapore and Tokyo, proving the concept of the shopping holiday to get cheaper goods abroad may be misguided. London is actually only the 48th most expensive city in the world and is in fact the cheapest place anywhere to buy tea bags. They'll cost £3.22 for 250 grams, compared to £5.40 in Sydney.New research has rated worldwide cities according to the cost of livingIt takes into account consumer items but not property or childcare costsLondon doesn't even make the top 50 and is the cheapest city to buy teaThe most expensive city is Juba in South Sudan because of exchange rate
