Topic-wise questions in SSC CGL 2025 Tier 1 Quant

What this tells you: course of action

• Begin with Mensuration and Geometry. These carry about 52% of the questions, which makes them the best place for your first study sessions.
• Keep in rotation: Trigonometry, Algebra and Simple & Compound Interest, a steady 32% that rewards regular practice once the first group feels comfortable.
• Save for the end: 4 one-question topics (16% together). Skim them last rather than building long study blocks around them.
• Splitting your study time: out of every 10 study sessions on this section, about 5 for the first group, 3 for the keep-in-rotation group and 2 for the leave-for-last group.

Key formulas behind this Quant section

• Sum of cubes: \( a^{3}+b^{3}=(a+b)^{3}-3ab(a+b) \)
• Volume of a hemisphere: \( V=\dfrac{2}{3}\pi r^{3} \)
• Diagonal of a cuboid: \( d=\sqrt{l^{2}+b^{2}+h^{2}} \)
• Direct common tangent: \( L=\sqrt{d^{2}-(r_{1}-r_{2})^{2}} \)
