JAMB Free Tutorial 2025 on Word Problem (PART 1)

As this topic requires understanding of letters and figures and how to manipulate them.
We at Edustuff want to eradicate the fears of students on this topic with simple questions.

What is Word Problem?

Word problem by definition are mathematical problems which are written in word.
Which means to solve word problem, you must understand some important words used.

Some of them are:

• Sum: Sum Is the result we get when we add two or more numbers together e.g  The sum of 20 and 17 is 37.

==========
The sum of 5,10 and 6 is 21
==========
The sum of 3 and a number is?
This is a basic problem.
We first assume the number to be  Letter “X”
So the sum of 3 and a number will be  X + 3.
=======
The sum of 5 and a number is equal to 25,find the number?
Difficult?
No it shouldn’t be!!
Let the unknown number be  x
So the sum of 5 and a number =25
X +5=25
X=25 – 5
X = 20
Check : 20 + 5 =25.
Easy??
Let’s move on

•  Difference : the result of subtracting one number from the other. It can be positive or negative

======≠=≠====

1. Positive difference : The positive difference between 24 and 10 is 14

It means the bigger number – smaller number
=============

2.Negative difference  : The negative difference between  2 and 5 means the smaller – bigger.
2 – 5 = -3

• PRODUCT : This is the result of multiplying two or more numbers

E.g : The product of 2 and 9 is?
Solution
=========
2 ✖ 9  = 18
===========
The product of  3 and a number gives 18,Find the number?
Simple right?
Let the number be  x or any arbitrary alphabet  as usual.. Let’s say A for this question
Product means multiplication
3 multiplied by a number =18
3 ✖  A =18
3A = 18
Divide both side by 3
3A =18
—– ——
3      3
A= 6
Check : 3✖ 6 = 18
==============
3 multiplied by the sum of 2 and a number gives 12. Find the number
Hard right.?
U have to stay calm and break down the questions
============
3 multiplied by the sum (X+2) gives 12

3(X+2) =12
Open the bracket by multiplying by 3

3X + 6 = 12
3X =12 – 6
3X = 6
Divide both side by 3
3X =6
—-  ——
3     3
X = 2
Check :
3(2+2)= 12
3 ✖4=12
12=12
Correct!!!!

•  Consecutive odds numbers : odd numbers that follow themselves in array e.g “1,3,5,7,9,11,13,15,17…

•  Consecutive even numbers : even numbers that follow themselves “2,4,6,8,10,12… 22,24,26… “

 Note: the difference between consecutive odd number is “1️⃣ ” while the difference between consecutive even is “2️⃣ “
