Maths and Science Exampler Problems and Solutions for Batch 2024-2025

Maths:
- Problem 1: Find the value of x in the equation 3x + 5 = 17.
Solution:
To solve for x, we need to isolate x by subtracting 5 from both sides of the equation.
3x + 5 - 5 = 17 - 5
3x = 12
Then, divide both sides by 3 to find the value of x.
x = 4
- Problem 2: If a circle has a radius of 5 cm, calculate its circumference.
Solution:
The formula for the circumference of a circle is C = 2πr, where r is the radius.
C = 2 * 3.14 * 5
C = 31.4 cm

Science:
- Problem 1: Define the term 'photosynthesis' and explain its importance in plants.
Solution:
Photosynthesis is the process by which plants convert light energy into chemical energy to produce food.
It is important for plants as it provides them with the necessary nutrients to grow and survive.
- Problem 2: Explain the concept of 'force' and provide examples of different types of forces.
Solution:
Force is a push or pull acting on an object. There are different types of forces, such as:
- Gravity: the force that pulls objects towards the center of the Earth.
- Friction: the force that opposes the motion of objects sliding past each other.
- Tension: the force that occurs when an object is pulled tight by forces acting from opposite ends.
These are just a few examples of the types of problems and solutions you may encounter in your exams. Make sure to practice similar problems to improve your understanding and performance in maths and science.
