| 95% | Modulo / day-of-week / clock problem — Translate to N mod 7 (or mod 12 for clock) · compute remainder · count forward/backward · state the named day/hour. | 2 MARKS |
| 90% | Allegation / mixture — Identify C, D, M · apply (D−M):(M−C) cross-rule · verify by weighted-average check · state ratio with units. | 3 MARKS |
| 85% | Boats and streams — Compute down + up speeds · apply b = (down+up)/2, s = (down−up)/2 · verify both consistency checks. | 3 MARKS |
| 80% | Pipes and cisterns (with leak) — Convert each pipe to a per-unit-time RATE · sum the rates (leaks are negative) · invert to get the combined time. | 3 MARKS |
| 75% | Numerical inequality from a word problem — Translate constraint into inequality · solve algebraically (FLIP sign when multiplying/dividing by negative) · interpret solution back in the word context. | 4 MARKS |
