Mental Calculations at Numerical Reasoning Tests

Numerical Reas oning tests test your numerical reason ing abilities; that is how well your mental processes allow you to manipulate data of numerical nature. Often these

tests comprise questions where you need to employ your mental arithmetic skills to process large am ount of data quickly and accurately. Below you can find som e hints

and tips as how you should s wift through large amount of data presented in tables, charts or graphs to comple te questions at numerical reaso ning tests in shortest time

possible.

Mental Calculation & Estimation

The below ques tions 1 and 2 tes t your abilities to process large amo unt of data quickly and accurately. For example, the ques tion 1 requires you to

conclude which project had the h ighest percentage profit. To quickly tackle this question, follow three sim ple s teps.

Glance at the table and insp ect all data provided

Mentally calculate and rule out projects that would have the lowest/highest percentage profit

On calculator calculate projects with highest percentage profits and make conclus ion

Table 1

Question 1

Which project had the highest percentage profit?

By thorough in spection we can conclude that Project B, C and E would have the lowest percentage p rofit compared to Project A and Project D. To find out

you need to look for projects with lowes t proportional operational costs to revenue. Starting with Project A; you can easily see that percentage revenue is

70% that is 21/30; whereas revenues of Project B, C and E wou ld be lo wer:

Project B 11/25 approximately 10/25 = 40% s o 11/25 would have to be slightly above 40%

Project C 15.5 / 31 = 50%

Project E 8/20 = 40%

The revenue of project D is 60% (3/5) and hence you may conclude that Project A mus t be the correct answer. Remem ber, you need make as many

calculations as poss ible in your head and to calculate only data with slight deviation with your calculator.

Table 1

Question 2

Which project had the lowest revenue to costs ratio?

By quick comparis on and mental es timation of total revenue and total costs of all projects you can quickly conclude that Project B and E m ust have lower

ratio than project A, C and D. That is:

Project A 30/9 equ als approximately to 3.3

Project B 25/14 equals approximately to 1.8

Project C 31/15.5 equals to 2

Project D 5/2 equals to 2.5

Project E 20/12 equals approximately to 1.7

Hence for your calculations you can rule out project A, C and D an d sa ve time by not imputing d ata into your calculator. To get the correct answe r use your

calculator only to calculate ratio of Projects B and Project E as the revenue to cost ratio of these are lo west and m ost sim ilar.
