Detailed Analysis of Sample Questions
To provide a more concrete understanding, let’s delve into some sample questions from the 2019 Half Yearly Question Paper and analyze their purpose and the skills they aim to test.
Multiple Choice Question
Example: If the product of two rational numbers is 1, and one of the numbers is 2/3, what is the other number?
- (a) 2/3
- (b) 3/2
- (c) -2/3
- (d) -3/2
Analysis: This question tests the student’s understanding of the multiplicative inverse property of rational numbers. The correct answer is (b) 3/2, as the product of 2/3 and 3/2 is 1.
Short Answer Question
Example: Solve the linear equation: 3x – 7 = 2.
Solution: Adding 7 to both sides, we get 3x = 9. Dividing both sides by 3, we get x = 3.
Analysis: This question assesses the student’s ability to manipulate and solve linear equations, a fundamental algebraic skill.
Long Answer Question
Example: Construct a quadrilateral ABCD where AB = 5 cm, BC = 6 cm, CD = 4 cm, DA = 7 cm, and AC = 8 cm. Measure angle A.
Solution: Class 8 Maths Half Yearly Question Paper 2019 The student needs to use a ruler and compass to construct the quadrilateral accurately and then measure the required angle.
Analysis: This question tests practical geometry skills, including the ability to accurately construct geometric shapes and measure angles.
Very Long Answer Question
Example: A shopkeeper sells a pair of shoes at a 20% profit. If the cost price is $50, find the selling price. Also, if the customer bought the shoes with a 10% discount on the selling price, what is the final amount paid?
Solution:
- Selling price without discount = Cost price + Profit = $50 + 20% of $50 = $50 + $10 = $60.
- Final amount paid with 10% discount = Selling price – Discount = $60 – 10% of $60 = $60 – $6 = $54.
Analysis: This problem integrates multiple concepts such as percentage, profit and loss, and discounts, testing the student’s ability to apply these concepts in practical situations.
Significance of the Half Yearly Examination
The Half Yearly Examination holds significant value in the academic calendar for several reasons:
- Assessment of Understanding: It provides a clear picture of the student’s grasp of the topics covered in the first half of the academic year.
