Let 'x' be the total family income then, Before the increment Richard's salary = (20%)(x) = 0.2 x After increment Richard's salary = (30%)(x) = 0.3 x The percentage points of the salary of Richard as a percentage of his family's total income increase can be calculated as, $$=\frac{\left(0.3x-0.2x\right)}{x}\times100\%$$ $$=\frac{0.1x}{x}\times100\%$$ $$=0.1\times100\%=10\%$$ It can also be calculated as 30%-20% = 10% Therefore, Option C is correct, Hope it helps.
