SSC CGL 2025 Tier 1 Quant PYQ – 20 Sep 2025 Shift 2 (25 Questions with Solutions)

SSC CGL 2025 Tier 1 Maths PYQ: 20 Sep Shift 2 Quantitative Aptitude Paper

SSC CGL 2025 Tier 1, 20 September 2025, Shift 2: this set reproduces that paper's Quantitative Aptitude section. Questions range from square roots and partnership to mensuration, coordinate geometry and trigonometric identities. On Aptitude360 every question comes with a full written solution.

What the 20 Sep 2025 Shift 2 Quant section covers

• Square roots of perfect squares and simplifying surds
• Partnership with added capital, profit sharing and salary allocation by percentage
• Compound growth to a multiple of the principal and simple interest for months
• Speed with a head start, mixtures of oils at different prices, combined filling rates
• Mensuration: painting surface area, tiling an L-shaped floor, triangle area from three sides, hexagon combinations, prism volume
• Coordinate geometry: line through two points and the circumcentre of a right triangle
• Trigonometry: complementary angles and the double-angle identity
• Number classification, polygon diagonals and shadow proportions

Key formulas and rules for this CGL Maths paper

• Heron's formula: \( \sqrt{s(s-a)(s-b)(s-c)} \), \( s=\dfrac{a+b+c}{2} \)
• Slope through two points: \( m=\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}} \)
• Right triangle: circumcentre is the midpoint of the hypotenuse
• Complementary angles: \( \sin\theta=\cos(90^{\circ}-\theta) \)
• Double angle: \( \cos 2A=1-2\sin^{2}A \)
• Compound growth: \( A=P\left(1+\dfrac{r}{100}\right)^{n} \)

How to revise these SSC CGL Quant topics

• When an amount becomes k times in a fixed period, it becomes k squared times in double that period under compound interest
• If the sine of one acute angle equals the cosine of another acute angle, the two angles add up to a right angle
• Split composite floors and shapes into simple rectangles before applying rates or discounts

Who should take this CGL Quant paper
