TN SSLC Passing Marks: Subject-Wise

To pass the Class 10 exam, you need to clear every subject separately. A high score in one subject does not make up for a low score in another. The table below shows the maximum marks and the minimum you need in each subject.

Please note that in Science, you have to pass the theoretical and practical sections independently. If you score below the minimum in either part, even when your total marks are more than 35, you will not pass Science. That is why it becomes important to practice Science questions along with Samacheer Kalvi 10th books solutions 2026-27.

Sample Samacheer Kalvi 10th Books Solutions 2026-27

Here is an example of how we provide these Tamil Nadu 10th textbook solutions. Every answer follows the method that helps you score full marks in the exam.

Maths Solution 

Question: What is the difference between a relation and a function?

Solution: A relation from set A to set B is any subset of A × B. A function is a special relation in which every element of A is related to exactly one element of B.

Example: Let A = {1, 2} and B = {3, 4}.

R = {(1, 3), (1, 4)} is a relation but not a function, since 1 is related to two elements and 2 to none.

f = {(1, 3), (2, 4)} is a function, since each element of A has exactly one image.

So every function is a relation, but not every relation is a function.

Science Solution

Question: Describe the structure of the human heart and explain how blood flows through it.

Solution: The human heart is a hollow, muscular organ that lies between the two lungs, slightly tilted to the left. It is enclosed in a double-walled membrane called the pericardium, which protects it from shocks.

• Chambers: The heart has four chambers. The two upper chambers, the atria, have thin walls and receive blood. The two lower chambers, the ventricles, have thick walls and pump blood out. The left ventricle has the thickest wall, since it pumps blood to the whole body.

• Valves: The tricuspid valve (right side) and bicuspid valve (left side) separate the atria from the ventricles. The semilunar valves guard the openings of the pulmonary artery and aorta. Together, they prevent blood from flowing backwards.

Flow of blood: Body → Vena cava → Right atrium → Right ventricle → Pulmonary artery → Lungs → Pulmonary veins → Left atrium → Left ventricle → Aorta → Body

Since blood passes through the heart twice in one cycle, this is called double circulation.

Social Science Solution

Question: Explain the causes of the First World War.

Solution: The First World War (1914 to 1918) was caused by long-standing tensions among European powers, which finally broke out after a single incident.

Long-term causes:

• Alliance system: Europe was divided into two rival groups: the Triple Alliance (Germany, Austria-Hungary, and Italy) and the Triple Entente (Britain, France, and Russia). A conflict involving one country could drag all its allies into war.

• Militarism: Major powers built up large armies and navies. The naval race between Britain and Germany increased suspicion and fear.

• Aggressive nationalism: Movements like Pan-Slavism and Pan-Germanism encouraged nations to dominate others, creating hostility, especially in the Balkans.

• Imperialism: Competition for colonies in Africa and Asia created rivalry, particularly between Germany and the older colonial powers, Britain and France.

Immediate cause: On 28 June 1914, Archduke Franz Ferdinand, heir to the Austro-Hungarian throne, was assassinated in Sarajevo by Gavrilo Princip, a Bosnian Serb. Austria-Hungary declared war on Serbia on 28 July 1914, and the alliance system soon drew the other powers into the war.
