# Thread: Ratio question: highest ratio of Avg Sales Price to Ave Production Cost

1. ## Ratio question: highest ratio of Avg Sales Price to Ave Production Cost

Hi

I'm working through some numerical reasoning tests and I am stuck on this ratio question.

I have the answer as show below, but I need to know how they got the ratios. I have enclosed the question.

Many thanks

 2010 2009 2008 2007 2006 Avg Sales Price 62709 60296 63188 51607 51602 Production cost 14500 15800 13600 11400 13750 ratio 4:3:1 3:8:1 4:6:1 4:5:1 3:8:1

How are you getting an answer with three values, when the question asks about a ratio of two values?

 2010 2009 2008 2007 2006 Avg Sales Price 62709 60296 63188 51607 51602 Production cost 14500 15800 13600 11400 13750 ratio 4:3:1 3:8:1 4:6:1 4:5:1 3:8:1
Are you saying that the last line is the ratios they gave as part of finding the answer? Either they were printed incorrectly, or you misinterpreted what it said. The ratios are found by simply dividing the first number by the second; it should look like this:

 2010 2009 2008 2007 2006 Avg Sales Price 62709 60296 63188 51607 51602 Production cost 14500 15800 13600 11400 13750 ratio 4.3:1 3.8:1 4.6:1 4.5:1 3.8:1

When you want to compare ratios, you don't want them as simplified ratios like 4:3, but as decimals (here written as "something:1"). They did that, rounding to the nearest tenth. The answer to the question is the one with the largest number, namely 2008.

I am just giving you the solution they provided. I just want to know how they worked out the answer i.e. how did they work out that the ratio was 4:3 for 2010

Yes I can see the answer is 2008, but how did they work it out. Thanks
