Types of Maths IQ Questions
Maths IQ questions can be categorized into several types. Understanding these categories can help you prepare better for various tests and assessments.
1. Arithmetic Questions
These questions test basic arithmetic operations such as addition, subtraction, multiplication, and division.
Example:
What is 25% of 200?
Answer:
To find 25% of 200, you can convert the percentage to a fraction:
25% = 25/100 = 1/4.
Now, calculate:
1/4 of 200 = 200 ÷ 4 = 50.
2. Algebraic Questions
Algebra questions often involve solving for unknown variables.
Example:
Solve for x in the equation: 2x + 5 = 15.
Answer:
To solve for x, first isolate the variable:
2x = 15 - 5
2x = 10
Now divide both sides by 2:
x = 10 ÷ 2 = 5.
3. Geometry Questions
Geometry questions involve shapes, sizes, and the properties of space.
Example:
What is the area of a triangle with a base of 10 cm and a height of 5 cm?
Answer:
The area of a triangle is given by the formula:
Area = (base × height) / 2.
So, substituting the values:
Area = (10 cm × 5 cm) / 2 = 50 cm² / 2 = 25 cm².
4. Logical Reasoning Questions
Logical reasoning questions involve patterns and sequences.
Example:
What is the next number in the series: 2, 4, 8, 16, ...?
Answer:
The pattern here is that each number is multiplied by 2.
So, the next number is:
16 × 2 = 32.
Practice Questions with Solutions
Here we provide a set of practice questions, along with their solutions.
Arithmetic Practice Questions
1. If you buy 3 notebooks for $2 each and 5 pens for $1 each, how much do you spend in total?
Solution:
Cost of notebooks = 3 × $2 = $6.
Cost of pens = 5 × $1 = $5.
Total cost = $6 + $5 = $11.
2. A car travels 60 miles in 1 hour. How far will it travel in 2.5 hours?
Solution:
Distance = Speed × Time.
Distance = 60 miles/hour × 2.5 hours = 150 miles.
Algebra Practice Questions
1. If 3x + 2 = 11, what is the value of x?
Solution:
3x = 11 - 2
3x = 9
x = 9 ÷ 3 = 3.
2. Solve for y in the equation: 5y - 7 = 3y + 5.
Solution:
5y - 3y = 5 + 7
2y = 12
y = 12 ÷ 2 = 6.
Geometry Practice Questions
1. What is the circumference of a circle with a radius of 7 cm? (Use π ≈ 3.14)
Solution:
Circumference = 2πr
Circumference = 2 × 3.14 × 7 cm = 43.96 cm.
2. A rectangle has a length of 10 cm and a width of 4 cm. What is its perimeter?
Solution:
Perimeter = 2(length + width)
Perimeter = 2(10 cm + 4 cm) = 2 × 14 cm = 28 cm.
Logical Reasoning Practice Questions
1. What is the missing number in the sequence: 5, 10, 20, ?, 80?
Solution:
The pattern is that each number is multiplied by 2.
So, the missing number is:
20 × 2 = 40.
2. A family has two boys and three girls. If they are to be seated in a row, how many different arrangements are possible?
Solution:
The total number of arrangements for 5 children is given by 5! (5 factorial).
5! = 5 × 4 × 3 × 2 × 1 = 120 arrangements.
Tips for Solving Maths IQ Questions
