Illustrative plan: a 3-hour paper worth 120 marks. How many minutes should the 20-mark cash-flow question receive?

Answer

30

Cells - Minutes to spend on the 20-mark question · ±0.5 180 ÷ 120 = 1.5 minutes per mark; × 20 = **30 minutes**. Put the real length and marks in on the day; the method is the answer.

Lyryx Intermediate FA Vol 1 (the Key Differences tables); ASPE s.3031, s.3061, s.3064, s.3400; authored — research.md §4, §8 (concept map O7–O8). The final’s length and marks are not on disk (gaps.md §1); the timing plan is a method with illustrative numbers.
