James is taking three examination papers in Spanish - OCR - GCSE Maths - Question 2 - 2020 - Paper 1

To find the lowest mark James needs in Paper 3 to achieve 60% of the total marks, we first calculate 60% of 240:

$$0.6 \times 240 = 144$$

James achieved 43 marks in Paper 1 and 38 in Paper 2. Adding these marks together:

$$43 + 38 = 81$$

Let x be the mark needed in Paper 3. To achieve a total of 144 marks, we set up the equation:

$$81 + x = 144$$

Solving for x gives:

$$x = 144 - 81 = 63$$

Thus, James needs at least 63 marks in Paper 3.
