are really easy to be done in a few seconds. in short: 1000* 1% = 10 2000 * 1% = 20 2000 * 0.5% = 10 in any case, regardless of this specific exercise, i wanted to show you this procedure of simplifying calculations and using only your mental arithmetic when a question asks about approximate results, because it may be very useful to you in other exercises too. 55
can suppose that we have only half a minute left to finish our exam, having to find the answer for this question really quickly. are you ready to play with the art and magic of numbers? let us go then! in this question, looking at our data, 10.75 and 0.48%, and knowing that we only need an approximate result, my reasoning would be: instead of 10.75 or 11, i can even take '10' for an approximate calculation, because we all know that mentally operating with multiples of 10 is faster and easier than with other figures. moreover, 0.48% is very close to 0.5%, and this last is exactly a half of 1%, another figure quite easy to handle. then, after my super-simplification, i should find a number, the gross national income, whose 0.5% (half 1%) is 10. considering figures '10' and '1%', my first thought is about 1000, because we quickly get that 1% of 1000 is 10. but i need a bigger number, whose half 1% is 10. consequently, my number has to be twice 1000; therefore, 2000. i mentally check that: 2000 * 1% = 20, so a half (2000 * 0.5%) is necessarily 10. finally, i can see that 2000 billion usd is a good estimate of the result, certainly good enough for me to select the right answer among the four options. even though you could think that this procedure is similar in extension or maybe longer than our first solution (which was already quite fast with only one division required with your calculator), please note that only the explanation of the reasoning is the longer part, while the mental operations 54
