PYQ Practice Set 1
Thirty-five solids questions as SSC set them: 12 from CGL 2025, 3 from Selection Post 2025, 7 from CGL 2024, 7 from CGL 2023 and 6 from CGL 2022, with the paper named after each one. This set leans on cuboids and rooms (painting walls, the longest rod in a room, a cake cut into cubes) and on questions where the lengths change by a percentage, and it has two frustum questions of the kind CGL 2025 asked in Tier 1. The last question is from Tier 2.
Allow about 25 minutes. Several answers are wanted in litres or m² while the data are in cm or m, so convert the units before you pick an option.
