What examiners said

Comprehensive responses • Most candidates correctly divided each term of the ratio by 6 or in stages by dividing by 2 and then by 3. • Division by 3 and by 2 was often more successful than a single division by 6. Limited responses • Some candidates indicated their intention to divide each term by 6, or in parts by 3 and by 2, then made an arithmetic error in one or more of the calculations, usual...

— Examiner report, February/March 2026, 0580/22 Q5(a) (Cambridge)

Comprehensive responses • Some candidates found the correct answer by forming equations with the unknowns and solving by use of algebraic techniques. For example, a + b + c + d = 40 → d – a = 12 → d = a + 12 Then b+c = 13 → b + c = 26 2 Substituting into the first equation a + 26 + a + 12 = 40 → a = 1 so d = 13 Reasoning b and c must be 13 and sum to 26 → b = 13 and c = 13 • Some candidates used s...
