Year when we have the highest differential GDP (America/EU): around 1980
North America GDP: 6200 ish
Europe GDP: 8200 ish
So when does North America hit 8200? (draw a line across to find out: looks like around 1990.
The closest answer choice is 9 years.
On questions like these don't hesitate to put your finger against the computer screen to make estimations...
Thanks for the reply,but the problem is we cant draw any lines during the test. When I tried to calculate I estimated it as 82-89 which is 7 yrs. Now both options are there 5 and 9. I am seeing lot of questions like this where we need to guess the graph readings and usually I end up doing wrong. Is there any technique for these questions other than using the naked eye?
I dont understand y such questions are coming up where we need to guess the values. (eg I have seen questions where I took the value as 320 and got the ans wrong. The solution was using 335 and you could hardly make out any diff between the 2 values on the graph). This is really frustrating.
Any advice to solve such questions???
