A+b=15----(1)
a*b=54----(2)
(1) a=15-b ----(3)
put(3) in(2)
(15-b)*b=54
15b-b^2=54
b^2-15b+54=0
(b-9)(b-6)=0
so b=9 or b=6
if b=9 then a=15-9=6
if b=6 then a=15-6=9
answer two numbers are 6 and 9
Numerical reasoning tests are often done to assess a person's ability to solve or interpret numerical data. A good source to train numerical reasoning is the use of computer education software's that deals with numerical data, the use of textbooks, self test etc.
<h3>What is done in Numerical reasoning tests?</h3>
Here, an individual is often required to analyze numerical data and then they are expected to draw conclusions from the data, which is often presented in tabular or graphical forms.
A person can improve their numerical reasoning by;
- Do make a study schedule and keep to it.
- Do Practice as if you are going for a competition, etc.
A way that a person can improve their speed in an numerical test is to reduce the time it takes a person to take in the information that is shown in the numerical reasoning questions.
