Hi, would appreciate some clarification on the question below: I got confused on how to answer it during a timed assessment. So I made a guess (site 2).

Can someone please explain how to work out this type of question (and show working out step-by-step). Thanks!

Divide the units produced by time taken. You can reduce the amount of calculations you do by seeing that site 1 produced less than site 2 in more time, so it must be less efficient than site 2 and you only need to work out units/hour to site 2 and 3

Divide the units created by the amount of minutes they used to make. So remember to convert the hours into minutes. Then just see which gets a higher efficiency or see if some get the same. By doing this you are getting the average amount of produce created in one minute by each company.

Thanks guys. I'm getting 459.25 for site 2, which is a higher value than site 3. Appears that I guessed correctly.

You also don't need to change it into minutes, as that would take more time which is essential in a NR test. You could keep hours as long as you remember 9 hours and 30 mins is 9.5

Thanks. I did it both ways, same result. Point taken! What is a NR test? Thanks.

Numerical reasoning
The key with these tests is to figure out ways to cut down on the number of calculations you do, because you will run out of time trying to do it properly!

Haha ... I'm a bit rusty. Thanks for the help. I will keep on practicing.

you can see that #1 cannot be the winner just by comparing it with #2

so it is between #2 and #3
