according to me the numerical test has 6 questions. my answers are.
1) D from first table Germany has a bigger population so the percentage may be lower but the number works out higher. (that confused me for a second)
2) 85thousand was the total of which 65k were standard. therefore 20k were not. therefore (20*100)/85=23.5.. hence answer is C
3) total population of italy and spain = 57.1m and 38.6m live births per 1000 =10.1 and 12.1 respectively. so for a thousand people there are so many kids born. soall you have to do is work out how many thousands make up the population of each. so eg for italy it is 57.1m/1000= 57100k people*10.1=576710 new borns for italy. therefore the answer for both of them together is-->1043770 round to the nearest thousand = C
4)just take away the births from the deaths. 56.6m/1000=56600*13.3=752780 births and 56600*11.8=667880 deaths. hence births-deaths=84900=answer B
5)Oct=100k total buttons of which 80 were standard. therefore 80000/100=800*5.70=$4560 for standard buttons and 200*$2.85=$570. the total sales for october is 4560+570=$5130. doing the same for november gives $4845+$285=5130. the answer should be no change ie E
6) total loss in sales over 6 months. so jsut take the total number of bad buttons produced for the six months in the graph. JUL-10k Aug-5k Sep-20k Oct-20k Nov-10k Dec-10k. A total of 75k bad buttons which sold for 750*2.85=$2137.5. had they been good they wouldve sold for 750*5.70=$4275. So the total loss due to bad buttons is 4275-2137.5=2137.5. ANSWER C
although i did it using the method above i couldve done them quicker by picking out small clues like they bad buttons sell for half the price of the good buttons. etc the best thing i find is to think for a second before the question to see if there are any clues. it does end up saving me a lot of mental calculation and time in the long run however long it is.
i feel like a nerd!!
