Identify mandatory card pair
Synthetic stack has height 360px. Offer card O and condition card Q each 160px, with 20px between adjacent cards. They must both appear together. Optional decorative card D also 160px. Local rule does not allow hiding Q or reducing its height.
| Cards | Height calculation | Fits 360 |
|---|---|---|
| O,Q | 160+20+160=340 | Yes |
| O,Q,D | 480+40=520 | No |
| O,D | 340 | Size fits; required Q absent |
Calculate stack height with gaps
- Select mandatory O/Q
- Count one gap for two cards
- Reject third card within this box
- Record O/Q rendition scope
A size-fitting pair without Q fails the supplied content condition.
How much height remains for the supported O/Q stack?
Show the worked answer
20px remain:360−340. Three cards exceed by 160px; choosing O/D would lose Q despite fitting height.
Preserve the condition in selection
| Case | Decision or result | Reason |
|---|---|---|
| O/Q with 340px | Accept | Both required cards fit |
| O/D with 340px | Reject | Condition Q omitted |
The handoff sheet names selected card IDs and total height. A count of two cards does not show that the correct pair was delivered.
