Chapter 01 Rational Numbers
Q. What is a rational number? Give the additive inverse of -5/7.
A rational number is any number that can be expressed in the form p / q where p and q are integers and q ≠ 0. The additive inverse of -5/7 is 5/7.
Jump to chapter
Chapter 02 Exponents
Q. Evaluate: (2/3)⁻³.
Using the negative exponent rule (a / b)⁻ⁿ = (b / a)ⁿ, we get (3 / 2)³ = 27 / 8 = 3.375.
Jump to chapter
Chapter 03 Squares and Square Roots
Q. Find the square root of 1764 using prime factorization.
1764 = 2² × 3² × 7² = (2 × 3 × 7)² = 42². Thus, √1764 = 42.
Jump to chapter
Chapter 04 Cubes and Cube Roots
Q. Find the cube root of 1728.
1728 = 2⁶ × 3³ = (2² × 3)³ = 12³. Thus, ³√1728 = 12.

Chapter 06 Sets
Q. What is a universal set?
A set containing all possible elements under consideration for any given discussion.

Chapter 07 Percent and Percentage
Q. Express 3/8 as a percentage.
(3 / 8) × 100% = 300 / 8 % = 37.5%.
Jump to chapter
Chapter 08 Profit Loss and Discount
Q. An article marked at ₹ 500 is sold for ₹ 450. Find the discount percentage.
Discount = Marked Price - Selling Price = 500 - 450 = ₹ 50. Discount % = (50 / 500) × 100 = 10%.
Jump to chapter
Chapter 09 Simple and Compound Interest
Q. Find the compound interest on ₹ 10,000 for 2 years at 10% per annum compounded annually.
Amount A = P(1 + R / 100)ⁿ = 10000(1 + 10 / 100)² = ₹ 12,100. CI = A - P = 12100 - 10000 = ₹ 2,100.

Chapter 10 Direct and Inverse Variations
Q. What is the characteristic equation for two quantities x and y in direct variation?
x / y = k (where k is a constant of proportionality).

Chapter 11 Algebraic Expressions
Q. Add the expressions: 3x + 4y and 2x - y.
(3x + 2x) + (4y - y) = 5x + 3y.

Chapter 12 Algebraic Identities
Q. Expand (x + 5)(x + 3) using standard algebraic identity.
Using (x + a)(x + b) = x² + (a + b)x + ab => x² + (5 + 3)x + (5 × 3) = x² + 8x + 15.
