A handset brand's share of a city's mobile phone sales rose from 24% to 30% over a year. By what per cent did its share increase?

Question

Accepted Answer

25%. The share rose by 30 - 24 = 6 percentage points, and a per cent increase is always measured against the EARLIER value: 6/24 = 1/4 = 25%. The trap is 6% - that is the rise in percentage POINTS, not a per cent increase. 20% divides by the new share (6/30) instead of the old one, and 24% merely repeats the starting share.
