# Simple Maths Question Help (Kenexa) watch

1. Please can somebody help me with the following math question? I have calculated the amount Japan should have as 18% of 192m, but when I subtract this from 192m, no answer is shown... am I doing the right thing?

Help is much appreciated. Thanks!

The question isn't how much the non-Japan part is worth, but what the difference is between the non-Japan part and the Japan part. Therefore, in effect you have to take away the 18% again to find the difference.

I actually think it is easier to deal in percentages for this question and then to change to actual values later. I would say that the Japanese part is 18%, so the non-Japanese part is 82%. Therefore the difference is 82%-18%=64% and get the actual value by doing 64% of 192m.
3. Thank you very much Sheldon - sorted it out now.

Firstly, you don't even have to do the calculation. The answer is clearly 271 because all the other answers are absolutely absurd, given the averages of each region range from 148 to 382 and so the answer must be in this range.

If you actually want to do the calculation, you have to bare in mind that there are more projects in Asia than in the other places etc. Therefore, you do (13*278)+(6*283)... to get the total amount of time spent on projects. You then divide it by the total number of projects, which is 33, to get the average time. I hope that makes sense.
6. Awesome! Thanks Sheldon

9. Got another Q for you guys!

I get 28.13... does that mean 'Cannot Say' is the correct answer? It's quite silly IMO as 'Cannot Say' implies that the data provided in the question isn't enough although I believe it is...?

Thanks

It is cannot say but the average speed isn't 28.13. You can't know what the average speed is because you don't know how long a car spends in each zone as it goes across the city. For example, it might spend 1 hour in the outer zone, 2 hours in the inner zone but only 10 minutes in the centre. As a result, you would have to put a higher weighting to the speed in the inner zone than in the centre when taking the average. As a result, the data provided in the question isn't enough and so the answer is cannot say. I hope that makes sense.
