Percentage change = (change ÷ original) × 100. Always divide by the original amount, not the new amount, unless the question asks something else.

Example: 40 to 50 is a change of 10; 10÷40 = 0.25 → 25% increase.

Matric tutors in Gulberg can drill five percentage-change stories until the structure is automatic.
