A's salary is increased first by 10%, then by 20%. The overall percentage increase from the original is
A35%
B30%
C32%
D33%
Answer & Solution
Correct answer: C. 32%
Successive: 1.10 × 1.20 = 1.32, so 32% increase. Formula: a + b + ab/100 = 10 + 20 + 200/100 = 32. Direct addition (30%) is wrong because percentages compound.
