Question 2: Circle Geometry

This page features a geometry question involving a circle, which is a typical topic in GCSE Maths Non Calculator revision Foundation and Higher tiers. The question provides a diagram of a circle with points A, B, and C on its circumference, and a tangent line at point A.

Students are asked to calculate the size of angle CAO, given that:

• Angle BAE = 56°
• Angle CBO = 35°

The solution involves several steps using circle theorems:

1. Angle BCA = 56° (angle between tangent and chord)
2. Angle BOA = 56° × 2 = 112° (angle at center is twice angle at circumference)
3. 360° - 112° = 248° (remaining angle in the circle)
4. 360° - 56° - 35° - 248° = 21° (final calculation for angle CAO)

Vocabulary: Tangent - a line that touches a curve at a single point without crossing it.

Highlight: Understanding circle theorems is crucial for solving geometry problems without a calculator.

Question 3: Volume and Rate Problem

This page presents a complex problem involving volume calculations and rates, which is characteristic of GCSE Maths non calculator topics Foundation and Higher levels. The question describes a swimming pool and asks whether it can be filled in 10 hours at a given rate.

Key information:

• Swimming pool dimensions: 10m × 10m × 1m
• Fill rate: 5 litres per second
• 1 m³ = 1000 litres

The solution involves multiple steps:

1. Calculate the volume of the pool: 10m × 10m × 1m = 100m³
2. Convert volume to litres: 100m³ = 100,000 litres
3. Calculate total seconds in 10 hours: 10 × 60 × 60 = 36,000 seconds
4. Calculate total litres filled in 10 hours: 36,000 × 5 = 180,000 litres

The conclusion is that the pool will not be completely filled in 10 hours, as it requires 200,000 litres but only 180,000 litres will be filled.

Example: This type of problem combines real-world applications with mathematical concepts, preparing students for practical problem-solving.

Question 4: Work Rate Problem

This page features a work rate problem, which is a common type of Non Calculator maths questions and answers Foundation and Higher tiers. The question states that 12 men can complete a job in 5 days and asks how long it would take 3 men to complete the same job.

The solution uses the concept of man-days:

1. Calculate total man-days: 12 men × 5 days = 60 man-days
2. Divide total man-days by new number of men: 60 ÷ 3 = 20 days

The question also asks students to state an assumption made in the calculation and how the answer would be affected if the assumption is not correct.

Highlight: Assumptions in mathematical modeling are crucial for problem-solving but can affect the accuracy of results if not valid.

Example: A common assumption in work rate problems is that all workers work at the same rate, which may not always be true in real-life scenarios.

Question 5: Algebraic Fraction and Expansion

This page presents an algebraic problem involving fractions and expansion, which is typical of GCSE Maths Non Calculator questions higher tier. The question asks students to work out an expression involving algebraic fractions.

The solution demonstrates step-by-step algebraic manipulation:

1. Find a common denominator
2. Add fractions
3. Simplify the resulting expression

Vocabulary: Algebraic fraction - a fraction where the numerator, denominator, or both contain algebraic expressions.

Highlight: Mastering algebraic fractions is essential for higher-level mathematics and is a key skill tested in non-calculator exams.

Question 6: Probability Tree Diagram

This page features a probability question using tree diagrams, which is a common topic in Non Calculator Maths Topics. The question involves a red 6-sided dice and a blue 8-sided dice, asking students to complete a probability tree diagram and calculate a specific probability.

Key points:

• The red dice can land on numbers 1 to 6
• The blue dice can land on numbers 1 to 8
• Students must calculate the probability that neither dice will land on a 6

The solution involves:

1. Completing the probability tree diagram with correct fractions
2. Calculating the probability of not landing on 6 for each dice
3. Multiplying these probabilities to find the combined probability

Definition: A probability tree diagram is a visual representation of all possible outcomes of an event and their probabilities.

Example: Probability tree diagrams are useful in various real-world scenarios, such as analyzing game strategies or predicting weather patterns.

Question 7: Percentage Increase Problem

This page presents a percentage increase problem, which is a key topic in GCSE Maths past papers PDF with answers. The question describes three rectangles (A, B, and C) where each subsequent rectangle has an area 10% greater than the previous one.

Students are asked to calculate by what percentage the area of rectangle C is greater than the area of rectangle A.

The solution involves:

1. Expressing the area of B in terms of A: B = A × 1.1
2. Expressing the area of C in terms of B: C = B × 1.1
3. Combining these to express C in terms of A: C = A × 1.1 × 1.1 = A × 1.21
4. Calculating the percentage increase: (1.21 - 1) × 100 = 21%

Highlight: Understanding compound percentage increases is crucial for many real-world applications, including financial calculations and population growth models.
